β-phenylselenocarbonyl compounds by a one-pot reaction of diphenyl diselenide and α,β-unsaturated ketones, aldehydes, esters and nitriles in the presence of indium metal-trimethylsilyl chloride under sonication. Presumably, the In-TMSCl reagent system reacts with diphenyl diselenide to form an intermediate, PhSeSiMe3, which then undergoes Michael addition with the α,β-unsaturated carbonyl compounds to produce
已经开发了一种简单方便的方法,在金属铟-三甲基甲硅烷基氯的存在下,通过二苯二硒化物与α,β-不饱和酮,醛,酯和腈的一锅反应,合成β-苯基硒代羰基化合物。据推测,In-TMSCl试剂系统与二苯二硒化物反应形成中间体PhSeSiMe 3,然后将其与α,β-不饱和羰基化合物进行迈克尔加成反应,生成产物。
