Abstract

Dialkyl phosphorocyanidates (2) were obtained from dialkyl phosphorochloridates (1) in high yield (80-86%) at room temperature in methyl cyanide. Reaction between diethyl phosphorochloridate and potassium cyanide was greatly influenced by the solvents used. Tetraethyl pyrophosphate also was found to react with potassium cyanide to give diethyl phosphorocyanidate in methyl cyanide.
