A direct synthetic method for cyanohydrin esters from aroyl chlorides using potassium hexacyanoferrate(II) as an eco-friendly cyanide source and tributylphosphine as a promoter is described. This protocol has advantages of no use of strong toxic cyanatingagents, high yield, and simple work-up procedure.

The reductive coupling of acyl cyanides promoted by alkyl phosphines has been discovered. Under mild reaction conditions, the substituted cyanohydrins were obtained in moderate to high yields by using trimethylphosphine or tributylphosphine as a promoter. The possible mechanism involved in the reaction was discussed on the basis of deuterium labeling and control experiments, indicating that one hydride
