the presence of CsF in N,N-dimethylformamide to give a mixture of methyldiphenylphosphine (2), (2,2-diphenyl-2-trimethylsiloxyethyl)diphenylphosphine (3) and (2-hydroxy-2,2-diphenylethyl)diphenylphosphine (4) in good yield. The use of about 10 mol% of CsF gave 3 with fairly good selectivity. The reaction with benzaldehyde gave a similar result, but only protodesilylation occurred in the reaction with
在 CsF 存在下,在 N,N-二甲基甲酰胺中,使二苯基(三甲基甲硅烷基甲基)膦(1)与二苯甲酮反应,得到甲基二苯基膦(2)、(2,2-二苯基-2-三甲基甲硅烷氧基乙基)二苯基膦(3)的混合物和(2-羟基-2,2-二苯基乙基)二苯基膦(4)收率良好。使用约 10 mol% 的 CsF 得到具有相当好的选择性的 3。与苯甲醛的反应得到类似的结果,但在与可烯醇的羰基化合物的反应中仅发生原脱甲硅烷基化。
