Abstract
![]()
While the formation
and breaking of transition metal (TM)–carbon
bonds plays a pivotal role in the catalysis of organic compounds,
the reactivity of inorganometallic species, that is, those involving
the transition metal (TM)–metalloid (E) bond, is of key importance
in most conversions of metalloid derivatives catalyzed by TM complexes.
This Review presents the background of inorganometallic catalysis
and its development over the last 15 years. The results of mechanistic
studies presented in the Review are related to the occurrence of TM–E
and TM–H compounds as reactive intermediates in the catalytic
transformations of selected metalloids (E = B, Si, Ge, Sn, As, Sb,
or Te). The Review illustrates the significance of inorganometallics
in catalysis of the following processes: addition of metalloid–hydrogen
and metalloid–metalloid bonds to unsaturated compounds; activation
and functionalization of C–H bonds and C–X bonds with
hydrometalloids and bismetalloids; activation and functionalization
of C–H bonds with vinylmetalloids, metalloid halides, and sulfonates;
and dehydrocoupling of hydrometalloids. This first Review on inorganometallic
catalysis sums up the developments in the catalytic methods for the
synthesis of organometalloid compounds and their applications in advanced
organic synthesis as a part of tandem reactions.

Abstract
Two compounds containing carbazole and sulfone groups with different alkyl chain lengths have been designed and synthesized. The sulfone group has strong absorption characteristics and the alkoxy chain and carbazole group are electron-rich, forming D-δ-A-type symmetrical molecules. The molecules have the characteristics of charge transfer and high thermal stability, and the molecules stack to form a layered staggered stack, reducing the intermolecular π-π interactions. The target compounds also exhibit strong ultraviolet-fluorescent emission in the solid state at room temperature, and they are expected to be good luminescent materials.

Abstract
A new method for the repetitive batch silylative coupling (trans-silylation) of vinylsilanes with vinyl boronates in the presence of Ru(CO)Cl(H)(PCy3)2 immobilized in poly(ethylene glycols) (PEGs) has been developed. Three PEGs (PEG600, PEG2000, and MPEG2000) with different molecular weights and end groups (MW = 600-2000) were tested as solvents and immobilization media, while an aliphatic solvent (n-hexane or n-heptane) or supercritical CO2 was used for product extraction. By applying 2 mol % of the Ru-H catalyst, it was possible to carry out up to 15 complete runs, with the predominant formation of 1-boryl-1-silylethenes. This immobilization strategy permitted for catalyst reuse and obtaining higher TON values (approximately 660-734) compared to the reaction in conventional solvents (∼50). Detailed kinetic studies of the most effective catalytic system were performed to determine catalyst activity and stability. Moreover, the reactions were carried out in an MPEG2000/scCO2 biphasic system, positively influencing the process sustainability.

Abstract
The first, recyclable protocol for the selective synthesis of (E)-alkenyl boronates via borylative coupling of olefins with vinylboronic acid pinacol ester in monophasic (cat@IL) or biphasic (cat@IL/scCO2) systems is reported in this article. The efficient immobilization of [Ru(CO)Cl(H)(PCy3)2] (1 mol%) in [EMPyr][NTf2] and [BMIm][OTf] with the subsequent extraction of products with n-heptane permitted multiple reuses of the catalyst without a significant decrease in its activity and stability (up to 7 runs). Utilization of scCO2 as an extractant enabled a significant reduction in the amount of catalyst leaching during the separation process, compared to extraction with n-heptane. Such efficient catalyst immobilization allowed an intensification of the processes in terms of its productivity, which was indicated by high cumulative TON values (up to 956) in contrast to the traditional approach of applying volatile organic solvents (TON = ~50–100). The reaction was versatile to styrenes with electron-donating and withdrawing substituents and vinylcyclohexane, generating unsaturated organoboron compounds, of which synthetic utility was shown by the direct transformation of extracted products in iododeborylation and Suzuki coupling processes. All synthesized compounds were characterized using 1H, 13C NMR and GC-MS, while leaching of the catalyst was detected with ICP-MS.

Abstract
A series of novel 1-(N-indolyl)-1,3-butadienes, as (1 : 1) mixtures of the (E) and (Z) dienes, was prepared in one step by base-catalysed isomerization of N-alkylindoles with a terminal butyne chain. The reaction conditions are mild, and in all cases the yields were very high (>90%). The (E) and (Z) dienes were separable by preparative TLC and could be fully characterized. This isomerization proceeded readily in the case of a butynyl chain, but didn't take place with a pentynyl chain. A mechanism was proposed for this reaction, based on previous studies on the isomerization of alkynes in basic media, and a key intermediate that supports the proposed mechanism could be isolated and fully characterized. A theoretical study of the proposed mechanism was performed by computational methods and the results validated the proposal. The reactivity of the synthesized dienes was studied in Diels–Alder reactions with p-benzoquinone, to obtain a small library of new 5-(N-indolyl)-1,4-naphthoquinones.The lack of reactivity in the case of the (Z) isomers was explained by calculation of the rotational curves of the central bond of the (Z) and (E) dienes. Finally, the cytotoxicity of the new 5-(N-indolyl)-1,4-naphthoquinones was tested against a panel of three cell lines. A series of novel 1-(N-indolyl)-1,3-butadienes, was easily prepared in one step and used for the synthesis of 5-(N-indolyl) naphthoquinones.![]()

Abstract
Tetra and octa substituted novel zinc(II) phthalocyanines (3a and 5a) bearing carbazole groups were synthesized by cyclotetramerization of respective phthalonitrile derivatives (3 and 5). The zinc(II) phthalocyanines (3a and 5a) were converted into the water-soluble quaternized derivatives (3b and 5b) by utilizing dimethylsulphate as quaternizing agent. The synthesized novel compounds were confirmed thruogh FT-IR, UV-vis and MALDI-TOF mass spectroscopic data and elemental analysis as well. The photophysical (fluorescence quantum yields and lifetimes) and photochemical (singlet oxygen generation) properties of new phthalocyanines were determined in dimethylsulfoxide (DMSO). The photophysical and photochemical results were compared according to the number of the carbazole groups on the phthalocyanine core. Additionaly, in vitro photocytotoxicity of the targeted compounds were examined against to hepato cellular carcinoma (HuH-7) cancer cell line for determination of their photosensitizing ability.

Abstract
A series of 11 different boron-dipyrromethene (BODIPY) dimers is carefully examined by means of ab initio and Tamm-Dancoff approximated density functional theory methods. Vertical and 0-0 excitation energies along with the tetraradical character of these dimers are determined. Possible application of a series of linked dimers for photodynamic therapy (PDT) was investigated through computing their excitation energies, spin-orbit coupling matrix elements, and singlet-triplet energy gaps. Finally through a systematic investigation of a series of 36 different BODIPY and aza-BODIPY dimers, a new class of near-IR heavy atom free photosensitizers for PDT action is introduced.

Abstract
In the title mol-ecule, C(26)H(25)Br(3)N(2), a dihedral angle of 6.15 (10)° is present between the carbazole and benzene ring systems with an E conformation about the C=C bond [1.335 (4) Å]. The butyl group is almost perpendicular to the carbazole plane [C-N-C-C torsion angle = -98.7 (3)°]. In the crystal, supra-molecular double chains along [-7,18,-16] are formed via C-H⋯Br and π-π inter-actions [centroid(carbazole five-membered ring)⋯centroid(carbazole six-membered ring) distance = 3.6333 (13) Å].

Abstract
The title compound, C(54)H(48)N(2)O(2), lies about an inversion centre. The carbazole ring system makes dihedral angles of 58.43 (7) and 88.96 (7)°, respectively, with the adjacent and central benzene rings. The dihedral angle between the two benzene rings is 52.01 (8)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O inter-actions, forming a tape along the a axis. The methyl group is disordered over two sets of sites with occupancies of 0.63 (3) and 0.37 (3).

Abstract
The aim of this review is to present the latest developments in the stereoselective synthesis of conjugated dienes, covering the period 2005-2010. Since the use of this class of compounds is linked to the nature of their appendages (aryls, alkyls, electron-withdrawing, and heterosubstituted groups), the review has been categorized accordingly and illustrates the most representative strategies and mechanisms to access these targets.

Abstract
The C-Si bonds of triisopropylsilyl-substituted alkenes, 1,3-dienes, and related multifunctional substrates, as well as analogous C-TBDPS and C-TBS bonds, are readily and chemoselectively cleaved with NIS (or other sources of I(+), such as N-iodosaccharin, 1,3-diodohydantoin, and Ipy(2)BF(4)). The desired iodoalkenes are obtained stereospecifically without byproducts, provided that the reactions are carried out in CF(3)CHOHCF(3) and, in general, with 30 mol % of Ag(2)CO(3) (or AgOAc/2,6-lutidine) as an additive. Fragment C10-C18 of cytotoxic amphidinolides B1-B3 and D has been synthesized using this improved procedure.
