A simple and efficient Rh-phosphinite complex catalyst was studied for the selective hydroformylation of various olefins. The influence of various reaction parameters including the effect of temperature, pressure, catalyst loading, time, and solvents was studied. The protocol was also applied for the synthesis of various acetals via tandem hydroformylation–acetalization of olefins in alcohols as solvents
研究了一种简单有效的Rh-次膦酸酯络合物催化剂,用于各种烯烃的选择性加氢甲酰化。研究了各种反应参数的影响,包括温度,压力,催化剂负载量,时间和溶剂的影响。该方案还适用于通过串联加氢甲酰化反应制得的各种缩醛,即在溶剂醇中的烯烃缩醛化反应。在不存在助催化剂且底物与催化剂摩尔比可观的情况下(TON 2500),可获得高活性和高选择性的缩醛形成。所开发的方案适用于各种烯烃,以在优化的反应条件下合成相应的醛和缩醛。
