in the presence of primary and secondary amines afforded N-Alkyl or N,N-dialkylthioformamides 5, and similar heating of 1 in the absence of amines afforded an inseparable mixture of acyclic polysulfides 4 bearing a thioformanilide moiety on each terminal. Bisthioformanilides 4 were also converted into 5 by treating with these amines, and the thioformylation was assumed to proceed through a pathway
在伯胺和仲胺存在下加热 N-芳基-1,2,3,4,5,7-五噻唑烷 1 得到 N-烷基或 N,N-二烷基硫代甲酰胺 5,并在不存在胺的情况下对 1 进行类似加热提供了在每个末端带有硫代甲酰苯胺部分的无环多硫化物 4 的不可分离的混合物。双硫甲酰苯胺 4 也通过用这些胺处理转化为 5,并且假定硫甲酰化通过涉及 1 的环裂变和随后这些胺亲核攻击 4 的硫甲酰基的途径进行。
