The stereochemistry of organometallic compounds. XXIV. Nickel(0)-catalysed additions of hydrogen cyanide to alkynes

Abstract

Hydrogen cyanide will add to alkynes bearing a wide range of substituents with cis stereospecificity, high regioselectivity, and in moderate-to-good yields, when the reaction is catalysed by tetrakis- (triphenyl phosphite)nickel(0).
