摘 要:本文对取代苯甲醛与硝基甲(乙)烷的缩合进行了初步探讨,并对缩合物以克莱门森法进行了还原、得到了下列初步结论:(1)羟基苯甲醛能否与硝基甲(乙)烷缩合成β—硝基取代苯乙(丙)烯,是由羟基所在芳醛环上的位置决定的,当羟基在间位或对位时,可得预期的产物,但在邻位时,则否。(2)用克莱门森法还原,由芳醛与硝基甲烷的缩合物得到的是胺,由芳醛与硝基乙烷的缩合产物得到的是甲基酮。The condensations of Substituted benzaldehydes with nitromethane, or nitroethane were studied.The obtained compounds were reduced by Clemmensen's method.Two preliminary conclusions were obtained. (1)Codensation of substituted hydroxyl benzaldehyde With nitromethane or nitroethane produced expected w—nitrostyrenes was cletermined by position- of hydroxyl,There were expected nitrostyrenes,when hydroxyl was meta or para,there were not expected nitrostyrens when hydroxyl was ortho. (2)Reducing of w-nitrostyrenes by Clemmensen's method,the Corrsp- ondig Substituted phenylethylamine were obtained,Reducing of Substituted 1- phenyl-2-nitro-propene corresponding Substituted 1-phenyl-2-propanone were obtained.
