Abstract
Two or more indole molecules tailored to a single non-metal central atom, through any of their C2–7 positions are not only structurally engaging but also constitute a class of important pharmacophores. Although the body of such multi-indolyl non-metallide molecules are largely shared to the anticancer agent bis(indolyl)methane, other heteroatomic analogs also possess similar medicinal properties. This concise review will discuss various catalytic and uncatalytic synthetic strategies adopted for the synthesis of the non-ionic (non-metallic) versions of these important molecules till date.

Abstract
Pd-catalyzed C-H arylation of heteorarenes is an important and widely studied synthetic transformation; however, the regioselectivity is often substrate-controlled. Here, we report catalyst-controlled regioselectivity in the Pd-catalyzed oxidative coupling of N-(phenylsulfonyl)indoles and aryl boronic acids using O2 as the oxidant. Both C2- and C3-arylated indoles are obtained in good yield with >10:1 selectivity. A switch from C2 to C3 regioselectivity is achieved by including 4,5-diazafluoren-9-one or 2,2'-bipyrimidine as an ancillary ligand to a "ligand-free" Pd(OTs)2 catalyst system. Density functional theory calculations indicate that the switch in selectivity arises from a change in the mechanism, from a C2-selective oxidative-Heck pathway to a C3-selective C-H activation/reductive elimination pathway.

Abstract
Transition-metal catalyzed cross-coupling reactions have emerged as a powerful tool for constructing biaryl compounds. Aryl halides and aryl metallic reagents (typically prepared from aryl halides) are used as coupling partners. It would be desirable to replace either aryl halide or aryl metallic reagents used in cross-couplings reactions with more readily available surrogates. Oxidative dehydrogenative cross-coupling between two different "inert" aryl C-H bonds represents an ideal system that would revolutionize cross-coupling chemistry. Furthermore, cross-coupling reactions might be improved by developing new catalytic protocols based on cheap transition-metal catalysts or even transition-metal-free systems to decrease costs and avoid the use of heavy metal and noble transition metals. It would be desirable to promote both catalytic systems and replace either or both coupling partners. We have used different strategies to improve cross-coupling reactions for constructing biaryls, which we categorized into four groups as follows. First, we focused on developing methodologies to be applied to easily produced and naturally abundant arenol-based electrophiles in cross-coupling via C-O activation. We have extended coupling partners to aryl carboxylates and arenols. Direct application of arenes as surrogates for organohalides and organometallic reagents avoids the tedious preparation of these reagents from arenes and considerably reduces the cost of starting materials. We have also explored cross-coupling reactions of arenes with various organometallic reagents, such as arylboronic acids, arylsilanes, and aryl Grignard reagents. Second, we summarize oxidative cross-coupling reactions based on C-H activation with aryl metallic reagents. On the basis of the reactivity patterns of different organometallic reagents, we adapted different catalytic systems to achieve effective cross-coupling reactions. Third, we improved a well-developed cross-coupling between arenes and organohalides through a strategy of replacing one coupling partner and using a new catalytic system. We have applied earth-abundant transition metals, such as Fe, and Co, and even developed transition-metal-free catalytic systems. Finally, our ultimate goal is to construct biaryls by cross dehydrogenative arylation between two different arenes. Owing to the structural similarity of both arenes, in particular two substituted benzenes, the greatest challenges are not only achieving regio- and chemo-selective C-H activation reactions but also matching both the reactivities and selectivities of both substrates to avoid homocouplings of either arene. Through our efforts, we have developed and applied four different strategies by introducing directing groups, controlling electronic and steric properties, and using dual directing strategies. We hope our studies will stimulate interest and new thinking on cross-couplings reactions for building carbon-carbon bonds from readily available and inexpensive chemicals from basic petroleum chemistry and nature.

Abstract
Reactivity of 1,3-disubstituted indolyl compounds with lithium reagents was studied to reveal the substituents and solvent effects on coordination modes and reactivities resulting in different indolyl lithium complexes. Treatment of 1-alkyl-3-imino functionalized compounds 1-R-3-(R'N═CH)C8H5N [R = Bn, R' = Dipp (HL1); R = Bn, R' = tBu (HL2); R = CH3OCH2, R' = Dipp (HL3); Dipp = iPr2C6H3] with Me3SiCH2Li or nBuLi in hydrocarbon solvents (toluene or n-hexane) produced 1,3-disubstituted-2-indolyl lithium complexes [η1:(μ2-η1:η1)-1-Bn-3-(DippN═CH)C8H4NLi]2 (1), {[η1:(μ3-η1:η1:η1)-1-Bn-3-(tBuN═CH)C8H4N][η2:η1:(μ2-η1:η1)-1-Bn-3-(tBuN═CH)C8H4N][η1:(μ2-η1:η1)-1-Bn-3-(tBuN═CH)C8H4N]Li3} (2), and [η1:η1:(μ2-η1:η1)-1-CH3OCH2-3-(DippN═CH)C8H4NLi]2 (3), respectively. The bonding modes of the indolyl ligand were kept in 1 by coordination with donor solvent, affording [η1:(μ2-η1:η1)-1-Bn-3-(DippN═CH)C8H4NLi(THF)]2 (4). The trinuclear complex 2 was converted to dinuclear form with a change of bonding modes of the indolyl ligand by treatment of 2 with donor solvent THF, producing [η1:(μ2-η1:η1)-1-Bn-3-(tBuN═CH)C8H4NLi(THF)]2 (5). X-ray diffraction established that compounds 1, 3, 4, and 5 crystallized as dinuclear structures with the carbanionic sp2 carbon atoms of the indolyl ligands coordinated to lithium ions in a μ2-η1:η1 manner, while compound 2 crystallized as a trinuclear structure and the carbanionic atoms of the indolyl moieties coordinated to lithium ions in μ2-η1:η1 and μ3-η1:η1:η1 manners. When the lithiation reaction of HL1 with 1 equiv of nBuLi was carried out in THF, the monomeric lithium complex {η1:η1-1-Bn-3-(DippN═CH)-2-[1'-Bn-3'-(DippNCH)C8H5N]C8H4NLi(THF)} (6) having coupled indolyl moieties was obtained. The compound 6 can also be prepared by the reaction of 1 with 0.5 equiv of HL1 with a higher isolated yield. Accordingly, the lithium complexes [η1:η4-1-Bn-3-tBuN═CH-2-(1'-Bn-3'-tBuNCHC8H5N)C8H4NLi(L)] (L = THF, 7a; L = Et2O, 7b) with the coupled indolyl moieties in η4 mode were isolated by treatment of HL2 with 2 in THF or Et2O. All complexes were characterized by spectroscopic methods, and their structures were determined by X-ray diffraction study.

Abstract
Heteroatom assisted C-H bond activation of 2-substituted naphthyridines with solvated Pd(I)2(CH3CN)6(BF4)2 provides bi- and trinuclear Pd(II) cyclometalated complexes, which provide valuable insight into potential intermediates in palladium catalyzed direct arylation reactions.

Abstract
π-Coordination of pyrrole or indole which lack a chelating functionality to a dinuclear Pd(I)-Pd(I) center is revealed. The dinuclear sandwich Pd(I)-Pd(I) complexes of pyrrole, N-methylpyrrole, or indole were synthesized and structurally characterized by X-ray crystallographic analysis. Indole employs the carbons of the six-membered ring in bridging π-coordination to a Pd(I)-Pd(I) center.
