A novel and efficient rhodium-catalyzed procedure for the preparation of silyl-substituted indenones has been developed. Using silanes and internal alkynes as the substrates, in the presence of CO, good to excellent yields of the desired indenones were isolated. A wide range of functional groups, encompassing esters, amines, nitriles and halides, is compatible in this system.
已开发出一种新颖且高效的铑催化方法来制备硅基取代的茚酮。以硅烷和内炔为底物，在一氧化碳存在下，可分离得到产率良好至优异的所需茚酮。该体系兼容多种官能团，包括酯基、氨基、腈基和卤化物。
