Reductive coupling of alkynes by oxobis(diethyldithiocarbamato)molybdenum(IV)-sodium borohydride

The reductive coupling of terminal alkynes and the intramolecular cyclization of diynes by oxobis(diethyldithiocarbamato)molybdenum(IV) in the presence of sodium borohydride are reported. The reaction leads to a mixture of products resulting primarily from 'head to tail' coupling of the alkynes. 1,7-Octadiyne undergoes cyclization to afford cycloheptene-3-ylidene in 45% yield. The product distribution appears to be controlled by steric factors associated with the alkyne-molybdenum intermediate.

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

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.
