Abstract
Structure-reactivity investigations and quantum-chemical parametrization of steric and electronic properties of geometrically constrained iminophosphoranes enabled the design of new frustrated Lewis pairs and revealed unusual properties at the phosphonium center embedded in the cage-shaped triptycene tricyclic scaffold.

Abstract
A mechanism of unusual tandem (MS/MS) fragmentation of protonated species of N-(triphenyl-λ5-phosphanylidene) derivatives, [M + H]+ to generate triphenylphosphine oxide (TPPO) within the mass spectrometer has been investigated and reported. Collision-induced dissociation of these molecules resulted in the generation of TPPO as a signature fragment. This fragment suggested the presence of a P-O bond in the structure which was contrary to the structure of the compound identified by nuclear magnetic resonance spectrometry (NMR) and single-crystal X-ray diffractometry (SXRD) techniques with a P═N bond rather than a P-O bond. In order to confirm the generation of the TPPO fragment within the mass spectrometer, 14 different N-(triphenyl-λ5-phosphanylidene) derivatives containing amide, 18O-labeled amide, thiamide, and nonacyl phosphazene derivatives were synthesized and their MS/MS behavior was studied by liquid chromatography-high-resolution mass spectrometry. Fragmentation of these amide derivatives generated TPPO/TPPS or their 18O-labeled analogues as the major fragment in almost all cases under similar MS conditions. Based on the outcome of these experiments, a plausible mechanism for such fragmentation, involving the intramolecular shifting of oxygen from carbon to phosphorus, has been proposed. DFT calculations for the protonated species at B3LYP-D3/6-31+G(d,p) further supported the proposed mechanism involving a four-membered ring, P-O-C-N, as the transition state. Details of this work are presented here.

Abstract
An efficient and scalable synthesis of N-perfluoroacylimino-λ3-iodanes was achieved via an unprecedented metathesis between iodosoarenes and perfluoroalkanenitriles. The perfluoroacylamino groups of the iodanes could be introduced to aromatic and heteroaromatic rings using photoirradiation.

Abstract
Organobismuth chemistry was emphasized in this review article due to the low price, low toxicity and low radioactivity characteristics of bismuth. As an environmentally-friendly class of organometallic compounds, different types of organobismuth compounds have been used in organic synthesis, catalysis, materials, etc. The synthesis and property characterization of many organobismuth compounds had been summarized. This review article also presented a survey of various applications of organobismuth compounds in organic transformations, as reagents or catalysts. The reactivity, reaction pathways and mechanisms of reactions with organobismuths were discussed. Less common and limiting aspects of organobismuth compounds were also briefly mentioned.

Abstract
A coordination polymer [Cp(O)2Mo-O-Bi(o-tolyl)2]n, II, containing Mo-O-Bi and Mo=O...Bi moieties was investigated with respect to its behavior in contact with OH- and Cp2MoH2 and as potential single source precursor in the polyol method. It turned out that hydroxide as a base breaks up the polymer to yield CpMoO3- and (o-tolyl)2BiOH. The latter polymerizes to give the coordination polymer [(o-tolyl)2BiOH]n, 1. Alternatively, 1 can be prepared by reacting [(o-tolyl)2Bi(hmpa)2]SO3CF3 with NBu4OH/H2O in thf/water. If, however, NBu4OH/MeOH is used in dichloromethane as the solvent, the (o-tolyl)2BiOH formed intermediately undergoes methanolysis, and finally, [(o-tolyl)2BiOMe]n, 3, is isolated. Although 1 and 3 are very similar compounds, their crystal structures differ significantly: while the structure of 1 is dominated by secondary bonding leading to seesaw-type coordination geometries around the Bi centers, the Bi atoms in 3 are coordinated in a distorted tetrahedral fashion, and secondary bonding plays only a minor role. If 1 is dissolved in a nonpolar, nonprotic solvent, condensation reactions occur immediately leading to [(o-tolyl)2BiOBi(o-tolyl)2], 2, which can be obtained on a preparative scale this way. Compound 3 which can be prepared in good yields may prove to be a useful starting material in bismuth chemistry. Here, it was shown to react with molybdocene dihydrides to provide stable Bi-substituted molybdocene monohydrides [(R)Cp2Mo(H)(Bi(o-tolyl)2)] (R = Me 4, R = H 5); compounds of that type were identified in solution before but had so far eluded isolation. Compound 4, whose crystal structure is discussed, also forms when II is treated with methylated molybdocene dihydride. This obviously leads to the formation of Mo-Bi bonds (--> 4), as well as Mo-OH units, which undergo condensation reactions leading to Mo-O-Mo moieties (i.e., [Cp2Mo2O5] is formed as a byproduct). The use of II as precursor in the polyol method successfully led to bismuthmolybdate nanoparticles (accompanied by crystallites); however, no single phase is obtained, but biphasic materials consisting of Bi(2)Mo2O9 and Bi2MoO6, whose ratio can be determined by the choice of the hydrolyzing reagent, are formed instead. One of these materials proved to be capable of sensing EtOH selectively at elevated temperatures.

Abstract
High-yielding syntheses of complexes based around the cyclodistibazane (Sb(2)N(2)) core are described from the reaction of organoantimony(V) chlorides with varying stoichiometric amounts of lithiated primary amines, LiN(H)R. Thus, mixing Ph(3)SbCl(2) with 2 equiv of LiN(H)R (R = CH(2)Ph) produces Ph(3)Sb(mu-NR)(2)SbPh(3) (1). Mixed amido/imido complexes of formula {R(H)N}Ph(2)Sb(mu-NR)(2)SbPh(2){N(H)R} (2) (R = CH(2)Ph, 2-OMe-5-(t)()Bu-C(6)H(3), and Cy) are made from the corresponding 3:1 molar ratio combination of LiN(H)R with Ph(2)SbCl(3). A similar reaction employing only 2 equiv of LiN(H)R (R = CH(2)Ph) with 1 equiv of Ph(2)SbCl(3) yields ClPh(2)Sb(mu-NR)(2)SbPh(2)Cl (3). Compounds 2a-c and 3 possess reactive functionality which may make them useful synthetic reagents in the preparation of more complex main group imido architectures. All of the complexes have been characterized by (1)H NMR spectroscopy, elemental analysis (CHN), and X-ray crystallography. An investigation of all known crystallographically characterized Sb-N fragments from the Cambridge Structural Database highlights a series of parameters that appear to influence the observed Sb-N bond lengths.

Abstract
Substituent effects on the oxidizing ability of triarylbismuth dichlorides were examined by intermolecular and intramolecular competition experiments on geraniol oxidation in the presence of DBU. It was found that the oxidizing ability of the dichlorides increases with increasing electron-withdrawing ability of the para substituents, and by introduction of a methyl group at the ortho position of the aryl ligands attached to the bismuth. The intermolecular and intramolecular H/D kinetic isotope effects observed for the competitive oxidation of p-bromobenzyl alcohols indicate that the rate-determining step involves C-H bond cleavage. Several primary and secondary alcohols were oxidized efficiently under mild conditions by the combined use of newly developed organobismuth(V) oxidants and DBU.
