Phase‐Transfer Catalyzed Pseudohalogenation of Phosphorochloridates

Abstract

Pseudohalogenation of phosphorochloridates by sodium pseudohalides with different phase transfer catalysts and solvents was optimized. Dialkyl and diaryl phosphorazidates phosphorocyanidates, and phosphor(isothiocyanidate)s were prepared in good yields from phosphorochloridates under two kinds of mild phase‐transfer catalyzed conditions respectively.
