用电喷雾质谱法测定了二个烷基化硫代钨酸盐[PPh4][(R-S)WS3](1:R=allyl;2:R=tBu)的离子质谱.结果表明,除了存在[(R-S)WS3]-阴离子,在两个化合物的溶液中均产生了一种新的物质--质子化硫代钨酸盐[(H-S)WS3]-阴离子.

용전분무질보법측정료이개완기화류대오산염[PPh4][(R-S)WS3](1:R=allyl;2:R=tBu)적리자질보.결과표명,제료존재[(R-S)WS3]-음리자,재량개화합물적용액중균산생료일충신적물질--질자화류대오산염[(H-S)WS3]-음리자.
Two alkylated thiotungstates,[PPh4][(R-S)WS3](1∶R=allyl;2∶R=tBu) in THF were examined by ESI mass spectroscopy.The results showed that besides the presence of the parent [(R-S)WS3]- anion, an interesting species,the protonated thiotungstate[(H-S)WS3]- anion, was detected to exist in both cases for the first time.
