n-C5H11, (CH3)2CH, (CH3)3C, C6H5, CH2CH, CH2C(CH3), (E)-CH3CHCH, (E)-C3H7CHCH, (E)-C6H5CHCH) have been carried out in the presence of Lewis acids such as Bu2SnCl2, BF3·Et2O and TiCl4. The stereochemical course of the reactions to give homoallylic alcohols does not necessarily depend on the formation of intermediate Lewis acid-aldehyde complexes, but rather upon the formation of allylmetal compounds
(E / Z)-Bu 3 SnCH 2 CH = CHCH 3与RCHO(R = CH 3,C 2 H 5,nC 3 H 7,nC 4 H 9,nC 5 H 11,(CH 3)2 CH之间的反应,(CH 3)3 C,C 6 H 5,CH 2 = CH,CH 2 = C(CH 3),(E)-CH 3 CH = CH ,(E)-C 3 H 7在路易斯酸例如Bu 2 SnCl 2,BF 3 ·Et 2 O和TiCl 4的存在下进行了CH 3 CH,(E)-C 6 H 5 CH 3 CH)。生成均烯丙基醇的反应的立体化学过程不一定取决于中间体路易斯酸-醛络合物的形成,而是取决于烯丙基金属化合物(例如Bu 2 ClSnCH 2 CH = CHCH 3,Bu 2 ClSnCH(CH 3)CHCH 2,氯3 TICH 2 CHCHCH 3等)是与羰基化合物反应的实际物质。Bu 3 SnCH 2 CH
