Abstract
Abstract Dialkyl phosphorocyanidates 2a–2g were prepared in high yield from dialkyl phosphorochloridates and hydrogen cyanide in the presence of triethylamine in ether. The white precipitates formed in the reaction of diethyl phosphorochlorodates and triethylamine were verified as triethylammonium chloride, not the similar phosphoryltriethylammonium chloride by FAB-MS, ESI-MS, 31 P-NMR, and 1 H-NMR.
