研究了35S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.

Isotopic exchange reactions of sulfur-containing compounds (i. e. carbon disulfide, thiophosphoryl chloride, ethyl phosphonothionic dichloride, phenyl phosphonothionic dichloride, diethyl phosphorochloride thionate, triethyl phosphorothionate, diethyl disulfide, ethyl mercaptan) with 35S in the presence of aluminum chloride were studied.
