Abstract

A new method for the formation of organohypophosphates containing a P–P bond under mild conditions, based on the DBU-assisted reaction of 2-alkoxy-2-thio-1, 3, 2- oxathiaphospholanes with O, O-dialkyl H-phosphonates or H-thiophosphonates, has been elaborated. The resulting triesters of P1-thio-and P1, P2-dithiohypophosphoric acids, respectively, having O-methyl or O-ethyl groups, can be selectively dealkylated to form the ...
