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.
Dimethylbenzoylmethylene sulfonium salt was synthesized from acetophenone in DMSO-HBr (dimethylsulfoxide-hydrogen bromide) system. The complex of Crystal structure. Dimethylbenzoylmethylene sulfonium salt can be converted to phenyl-ketone-dialdehyde in DMSO or DMSO-HBr system, which provides a new basis for the study of the oxidation mechanism of DMSO-HBr.
