A frustrated-Lewis-pair approach to catalytic reduction of alkynes to cis-alkenes

Frustrated Lewis pairs are compounds containing both Lewis acidic and Lewis basic moieties, where the formation of an adduct is prevented by steric hindrance. They are therefore highly reactive, and have been shown to be capable of heterolysis of molecular hydrogen, a property that has led to their use in hydrogenation reactions of polarized multiple bonds. Here, we describe a general approach to the hydrogenation of alkynes to cis-alkenes under mild conditions using the unique ansa-aminohydroborane as a catalyst. Our approach combines several reactions as the elementary steps of the catalytic cycle: hydroboration (substrate binding), heterolytic hydrogen splitting (typical frustrated-Lewis-pair reactivity) and facile intramolecular protodeborylation (product release). The mechanism is verified by experimental and computational studies.

Ni-catalyzed Si-B addition to 1,3-dienes: Disproportionation in lieu of silaboration

Upon attempted silaboration of acyclic 1- and 1,4-substituted 1,3-dienes, a new disproportionation reaction was discovered, yielding 1:1 mixtures of allylsilanes and dienylboranes. It was demonstrated that, as a key step in this new catalytic process, hyd

REDUCTIVE DIMERIZATION OF VINYL HALIDES IN AN Ni/Pb/Al THREE METAL REDOX SYSTEM. A FACILE ACCESS TO TERPHENYL DERIVATIVES

A novel three metal redox system, NiCl2(bpy)/PbBr2/Al, is found to be potent in the reductive coupling of vinyl halides, affording 1,4-biaryl-1,3-butadienes, precursors of terphenyl derivatives.
