Reaction of both terminal and cyclic alkenes have been shown to occur in a stereospecifically cis-manner with deuterium cyanide when a catalyst system based on Pd(DIOP)2 was used.Reactions of cyclohexene give only the products of equatorial cyanide incorporation.
The Stereochemistry of Organometallic Compounds. XXII The Stereochemistry of Metal-Catalysed Hydrogen Cyanide Addition to Olefins

Reactions of (E)-3,3-dimethyl(1,2-D2)but-1-ene with hydrogen cyanide and of (E)-3,3-dimethyl(1-D)but-1-ene with deuterium cyanide have been shown to proceed in a completely stereospecific cis fashion when a catalyst system based on Pd(diop)2 was used.Reaction between 4-t-butylcyclohexene and deuterium cyanide with the catalyst system gave only the equatorial nitriles trans-4-t-butylcyclohexane-1-carbonitrile and cis-3-t-butylcyclohexane-1-carbonitrile with cis incorporation of deuterium.Use of a catalyst system based on Ni4 and zinc chloride led to significant amounts of isotopic exchange and rearrangement.These results are compared with those from hydroformylation of the olefins, and the mechanism of hydrocyanation is discussed
