Abstract
A process for the preparation of compounds of the formula RBH.sub.3 CN wherein R is an alkali metal, a quaternary ammonium radical or a phosphonium radical wherein a compound of the formula RCN is treated with a stoichiometric amount or slightly less than a stoichiometric amount of a BH.sub.3 donor is described. The final products are useful as hydrolysis stable reductants and as synthetic intermediates.
Claims6
A process for the preparation of cyanoborohydrides having the formula:
- RBH.sub.3 CN
- wherein R is an alkali metal, a quaternary ammonium radical, or a phosphonium radical, said process comprising:
- (a) reacting a cyanide compound of the formula:
- RCN
- wherein R is a defined above, and a BH.sub.3 donor, and
- (b) heating the reaction product of (a) under refluxing conditions until substantially all of any isocyanoborohydride produced in step (a) is converted to cyanoborohydride.
