利用极性反转合成苄叉氯亚胺-1-α及苄叉氯亚胺的催化分解

Synthesis of Benzalchloroimine-1-d by Umpolung and Catalytic Decomposition of Benzalchloroimine

文献报导二苯基N-无取代硫亚胺(Ⅰ)和醛作用可得对应的腈,曾设想其机理如下Ph_(2)S-NH+PhCHO→←[Ph_(2)S-N-Ph-C-OH-H-Ph_(2)S-N=C■]→Ph_(2)S+PhCN+H_(2)O已知苄叉氯亚胺可分解成相应的腈,考虑到它在结构上与瞬时中间体B相似,如果在二苯硫醚共存下反应,可能形成结构上与B很相似的C。

This paper reports a simple preparative method of benzalchloroimine-1-d.The kinetic study on the reaction of benzalchloroimine I_(a-b) with diphenyl sulfide in benzene has been carried out.From,p value of Hammett equation and the kinetic isotope effect,its mechanism of reaction was tendered.
