ketone acceptors is enabled via hydrogenation of keto-enals with cationic rhodium catalysts. These results, in conjunction with prior studies involving the catalytic hydrogen-mediated reductive coupling of enones, dienes, and diynes with carbonyl acceptors, support the feasibility of developing a broad new class of catalytic C-C bond formations based on the electrophilic trapping of hydrogenation intermediates
金属酮醛酸酯与酮受体的第一催化交叉醛醇缩合是通过用阳离子
铑催化剂将酮-烯醛氢化而实现的。这些结果,再加上先前的研究,涉及烯酮,二烯和二炔与羰基受体的催化氢介导的还原偶联,支持开发基于亲电捕获氢化中间体的新型催化CC键的新方法。[反应:看文字]
