摘要 在DMSO-HBr(二甲基亚砜-溴化氢)体系中,以苯乙酮为原料合成得到二甲基苯甲酰亚甲基锍盐,用X射线单晶衍射法测定了该化合物的晶体结构.二甲基苯甲酰亚甲基锍盐在DMSO或DMSO-HBr体系中均可以转化为苯基乙酮醛,为DMSO-HBr氧化机理研究提供了新的依据. Dimethylphenacylsulfonium bromide was synthesized from acetophenone in DMSO-HBr (di- methyl sulfoxide-hydrogen bromide) system and its crystal structure was determined by X-ray diffraction analysis. Dimethylphenacylsulfonium bromide could be transformed to phenylglyoxal both in DMSO-HBr and DMSO system. These studies contributed new evidence for understanding the mechanism of the oxidation process in DMSO-HBr system.
