The first triphosphorus ligand has been designed and synthesized for highly regioselective linear hydroformylations. A very high l/b ratio (up to 471, 99.8% linear selectivity) was obtained in the linear hydroformylation of representative terminal and internal olefins. For the range of substrates tested, the regioselectivities achieved utilizing the novel triphosphoramidite ligand were much better
已经设计并合成了用于高区域选择性线性加氢甲酰基化的第一个三磷配体。在代表性的末端和内部烯烃的线性加氢甲酰化中获得了非常高的1 / b比率(高达471,线性选择性达99.8%)。对于所测试的底物范围,使用新型三磷酰胺基配体实现的区域选择性比双磷酰胺基配体的区域选择性好得多,并且接近四磷酰胺基配体的区域选择性。
