The treatment of silylenolethers with fluoroalkyl halides (Rf–X) in the presence of RhCl(PPh3)3 gave α-fluoroalkylated ketones. It seems that a rhodium complex derived from the silylenolether and RhCl(PPh3)3 played an important role for the oxidative addition of fluoroalkyl halides and the reductive elimination of the product.
在RhCl(PPh 3)3存在下用氟代烷基卤化物(R f –X)处理甲硅烷基烯醇醚,得到α-氟代烷基化的酮。似乎衍生自甲硅烷基烯醇醚和RhCl(PPh 3)3的铑配合物对于氟代烷基卤化物的氧化加成和产物的还原消除起着重要作用。
