Silica gel promoted, catalyst-free and solvent-free S-P, Se-P and Te-P bond formations are described. A variety of disulfides coupled with diarylphosphine oxides provide the corresponding phosphinothioates in excellent yields. For the first time, diselenides and ditellurides reacted with dialkyl phosphites under catalyst-free conditions to provide the corresponding phosphoroselenoates and phosphorotelluroates, respectively, in good to excellent yields.
Green synthetic method of thiohypophosphate
-
Paragraph 0014-0017, (2019/10/29)
The invention relates to a green synthetic method of thiohypophosphate as shown in the formula I as show in the specification, wherein R is phenyl, not more than three methyl or three methoxyl or three halogen substituted phenyl, straight-chain or branch-chain alkyl with no more than six carbon atoms, straight-chain or branch-chain alkenyl with no more then six carbon atoms, straight-chain or branch-chain alkynyl with no more than six carbon atoms and a 3 to 8-member aliphatic ring group; R is phenyl, not more than three methyl or three methoxyl or three halogen substituted phenyl, pyridyl, benzyl, naphthyl and a 3 to 8-member aliphatic ring group; according to the synthetic method, thiohypophosphate is a product directly obtained by enabling N-R thiophthalimide to react with di-R based phosphine oxide with water as a solvent.
