O, S) has been reinvestigated. The reaction wa shown to be highly stereospecific and proceeds with the retention of configuration at P via the thiocyanidate >P(O)SCN structure. The thiocyanidates rearrange into the isothiocyanidates >P(O)NCS with a rate of depending on structure of substrates and reaction conditions. The thiocyanation reaction of dialykl phosphite and their structural analogues offers
含有> P(X)H官能团(X = O,S)的有机磷化合物的硫氰化反应已得到重新研究。该反应显示为高度立体定向的,并通过硫氰酸酯> P(O)SCN结构保留在P的构型。硫氰酸酯以取决于底物结构和反应条件的速率重排为异硫氰酸酯> P(O)NCS。透析基亚磷酸酯及其结构类似物的硫氰化反应提供了一条通往异氰酸酯> P(X)NCS的极佳路线,在某些情况下,还提供了硫氰酸酯> P(X)SCN的极佳路线。
