Abstract

Diethyl α-thiocyanatophosphonates were prepared by the reaction of diethyl α-hydroxyphosphonates in good to high yields at room temperature by using triphenylphosphine, 2,3-dichloro-5,6-dicyanobenzquinone, and ammonium thiocyanate as a new and a neutral system.

Key words

thiocyanates - phosphonates - triphenylphosphine - ammonium thiocyanate - benzoquinone
