The reaction of two (organosilyl)methylmagnesium chlorides, R(CH32SiCH2MgCl (R = CH3 and C6H5), with silver chloride and with silver bromide in diethylether has been studied. It has been found that the reaction proceeds with the formation of significant amounts of compounds of the formula R(CH3)2SiCH2CH(CH3)OC2H5 in addition to the expected coupling products [R(CH3)2SiCH2-]2 and others. This result
研究了两种(有机甲硅烷基)甲基氯化镁R(CH 3 2 SiCH 2 MgCl(R = CH 3和C 6 H 5),氯化银和溴化银在乙醚中的反应。除了预期的偶合产物[R(CH 3)2 SiCH 2- ] 2以外,反应还会进行,从而形成大量式R(CH 3)2 SiCH 2 CH(CH 3)OC 2 H 5的化合物和别的。该结果表明,由格氏试剂引起的自由基对溶剂的攻击与自偶联反应同时发生。
