trimethylsilyl oxiranes(2), which on treatment with MgBr2Et2O gave 2-bromoacylsilanes(3) and either bromovinyl sulphones(5) or α,β-unsaturated acylsilanes(6) and 2-trimethylsilyl car☐ylic acids(7), depending on structure.
在氯代三甲基硅烷存在下,2-苯基磺酰基肟基(1)与丁基锂反应生成2-苯基磺酰基-2-三甲基甲硅烷基肟基(2),经MgBr 2 Et 2 O处理后生成2-溴酰基硅烷(3)和两种溴化砜基( 5)或α,β-不饱和酰基硅烷(6)和2-三甲基甲硅烷基羧基丙烯酸(7),具体取决于结构。
