pyridine-catalyzed reaction between a number of propanedioic acid derivatives 1 and thionyl chloride has been investigated in detail. Contrary to popular belief the straightforward formation of the corresponding α-chloro sulfenyl chlorides 2 is the exception rather than the rule. The propanediamide 2e, not available by the “standard” reaction of 1e with thionyl chloride, is surprisingly formed by reaction of 1e
已经详细研究了许多丙二酸衍生物1和亚硫酰氯之间的吡啶催化的反应。与普遍的看法相反,相应的α-氯亚磺酰氯2的直接形成是例外而不是规则。的丙二2E,不可用的“标准”反应1E与亚硫酰氯,令人惊讶地通过的反应形成1E与二氯化硫。已经证明了2作为硫代硫4前体的有用性。(©Wiley-VCH Verlag GmbH,69451 Weinheim,Germany,2002)
