研究了~(35)S与C=S、P=S、C—S—S—C、C—SH等类型硫化物用三氯化铝催化的交换反应。二硫化碳、硫代磷酰氯、乙基硫代膦酰二氯、苯基硫代膦酰二氯等用此法交换,均得到良好的化学产率与放射产率。二硫化碳或硫代磷酰氯与三氯化铝、硫共热,显示三个顺磁共振峰,因此初步推测交换反应为自由基反应。含有R—O—P键的P=S类化合物与三氯化铝发生副反应,故未能很好交换。二乙基化二硫的交换率颇低,乙硫醇则无交换。
The exchange reactions of ~ (35) S with C = S, P = S, C-S-S-C, C-SH and other sulfides catalyzed by aluminum trichloride were studied. Carbon disulfide, thiophosphoryl chloride, ethylthiophosphoryl chloride, phenylthiophosphoryl dichloride and so on by this method exchange, both good chemical yield and radioactive yield. Carbon disulfide or thiophosphoryl chloride and aluminum trichloride, sulfur heat, showing three paramagnetic resonance peaks, so preliminary speculated that the exchange reaction is free radical reaction. P = S containing R-O-P bonds and aluminum trichloride side reactions, it is not well exchanged. Diethylated disulfide exchange rate is low, ethanethiol no exchange.
