allylation product in the presence of a catalytic amount of the (cyclooctadiene)rhodium(I) chloride dimer [Rh(cod)Cl]2}, sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaBARF), and triphenyl phosphite [P(OPh)3] in refluxing 1,2-dichloroethane. Primary, secondary and tertiary benzyl acetates could be used for the reaction. Moreover, allylation of gem-benzyl acetate was possible with [Rh(cod)Cl]2, NaBARF
在催化量的(环辛二烯)氯化铑(I)二聚体[Rh(cod)Cl] 2 },四[3,5-双(三氟甲基)钠]存在下,乙酸苄酯与烯丙基三甲基硅烷反应生成烯丙基化产物苯基]硼酸酯(NaBARF)和亚磷酸三苯酯[P(OPh)3 ]在回流的1,2-二氯乙烷中。伯,仲和叔乙酸苄酯可用于该反应。此外,烯丙基化宝石-苄基乙酸酯是可能的的[Rh(COD)CL] 2,NaBARF,和P(OPH)3。Monoallylation和diallylation宝石-苄基乙酸酯可通过改变反应条件来控制。阳离子铑原位生成 作为路易斯酸催化剂,通过从苄基碳上消除乙酰氧基,得到苄基碳正离子化作用。
