chloroacetonitrile was confirmed to be N-(α,α,β-trichloroethyl)chloroacetamidine hydrochloride. The scope and limitations of the dimerization reaction of nitriles having α-hydrogen with HCl were studied. Most nitriles having α-hydrogen react with HCl to give N-(α-chloroalkenyl)alkylamidine hydrochlorides (3). Their hydrolysis to diacylamines (4) was also investigated.
重新研究了先前报道的几种稳定腈-HCl 盐的组成和结构。它们中的大多数已被发现具有 2RC≡N·2HCl 的组成,并已通过质量和 NMR 光谱分析确定为 N-(α-
氯烯基) 烷基脒盐酸盐 (3)。然而,来自
氯乙腈的 2:3 加合物被证实为 N-(α,α,β-三
氯乙基)
氯乙脒盐酸盐。研究了含α-氢的腈与HCl的二聚反应的范围和局限性。大多数含有 α-氢的腈与 HCl 反应生成 N-(α-
氯烯基) 烷基脒盐酸盐 (3)。还研究了它们
水解成二酰胺 (4)。
