Cyclic sulfates react with LiPPh2 to form a series of new amphiphilic or water-soluble ligands: monotertiary phosphines with one or two alkylene sulfate chains and ditertiary phosphines with one or two hydrophilic tails attached to bridgehead carbon atom; the application of zwitterionic RhI complexes (sulfatephos)2Rh(cod) and (sulfatediphos)Rh(cod) in liquid biphasic catalysis has been demonstrated for the hydroformylation of styrene and oct-1-ene.
环状硫酸酯与LiPPh2反应生成一系列新的两亲性或水溶性配体:具有一个或两个亚�烷基硫酸酯链的单三级膦以及具有一个或两个亲水性尾部与桥头碳原子相连的双三级膦;阴离子性铑I配合物(硫酸酯膦)2Rh(cod)和(硫酸酯双膦)Rh(cod)在液-液两相催化中应用于苯乙烯和1-辛烯的氢甲酰化反应。
