摘要 研究了在不同膦和氧化膦配体存在下铑催化的 1-辛烯加氢甲酰化反应。新膦配体芴基甲基苯基二苯基膦的分子结构由单晶 X 射线晶体学确定。研究了不同配体、配体与铑络合物的摩尔比、烯烃与铑络合物的比率、CO:H2混合物的压力和反应时间等参数。当使用膦配体作为辅助配体时,线性醛是主要产物,而当使用相关的氧化膦配体时,选择性变为支化产物。在优化的反应条件下,在[Rh(acac)(CO)(Ph3P)]-二(1-萘基)苯基氧化膦存在下,
An efficient P-arylation of secondary phosphine oxides has been achieved through the ligand-free copper-catalyzed addition of H–P(O) bonds to in situ generated arynes at room temperature. This transformation provides a straightforward route to the formation of the aryl–P bond with wide functional group compatibility, which produces arylphosphine oxides in up to 99% yield.
