Highly stereoselective metathesis reactions between optically active silyl compounds and copper(I) salts in 1,3-dimethyl-2-imidazolidinone (DMI) are reported. The substitution reaction of (+)-α-naphthylphenylmethylsilane with a mixture of lithium tert-butoxide and copper(I) salt smoothly proceeded in DMI to give the corresponding silyl ether with a high degree of retention of the configuration in a
据报道,光学活性甲硅烷基化合物与1,3-二甲基-2-咪唑啉酮(DMI)中的铜(I)盐之间具有高度立体选择性的复分解反应。在DMI中,(+)- α-萘基苯基甲基硅烷与叔丁醇锂和铜(I)盐的混合物的取代反应平稳地进行,从而以定量收率得到了具有高度保留构型的相应甲硅烷基醚。该反应需要使用DMI作为溶剂和存在氯离子。光学活性炔基硅烷也与混合试剂反应,得到相应的甲硅烷基醚。提出了氢硅烷的氧化加成和铜上甲硅烷基醚的还原消除的机理。
