摘要:
The compounds O,O-diethyl- and O,O-diisopropyl-S-benzylthiophosphite, 2-benzyl-thio-4,5-benzo-1,3,2-dioxaphospholane, diphenyl-S-benzylthiophosphinite, and S,S-dibenzylphenyldithiophosphonite were obtained. It was found that the thiophosphites enter into isomerization initiated by oxygen in the air; substitution together with isomerization is thereby observed in the case of thioesters of P(III) with the P-C bond. The interaction of thioesters of P(III) with oxygen is inhibited by spin traps.
