Abstract

Cyanide ion catalyzed addition of acylphosphonates to diethyl cyanophosphonate furnished phosphonocyanohydrin O-phosphates in high yield. The reaction works via the phosphonate-phosphate rearrangement, followed by the addition of diethyl ­cyanophosphonate to the cyanohydrin phosphate anion.
