[structure: see text]. A cationic rhodium(I)/dppb complex catalyzed direct intermolecular hydroacylation of N,N-dialkylacrylamides with both aliphatic and aromatic aldehydes has been achieved through the stabilization of acylrhodium intermediates by alkene chelation to rhodium. This method represents a versatile new route to gamma-ketoamides in view of the high atom economy and commercial availability
[结构:见文字]。阳离子铑(I)/ dppb络合物通过将烯烃与铑螯合来稳定酰基铑中间体,从而实现了N,N-二烷基丙烯酰胺与脂肪族和芳香族醛的直接分子间加氢酰化反应。考虑到高原子经济性和底物的商业可用性,该方法代表了一种通用的制备γ-酮酰胺的新途径。
