Cationic Rh(I)/Modified-BINAP-Catalyzed Reactions of Carbonyl Compounds with 1,6-Diynes Leading to Dienones and Ortho-Functionalized Aryl Ketones

We have determined that a cationic rhodium(I)/H8-BINAP complex catalyzes a [2 + 2 + 2] cycloaddition of both activated and unactivated carbonyl compounds with 1,6-diynes leading to dienones in high yields. On the other hand, unactivated aryl ketones react with 1,6-diynes in the presence of a cationic rhodium(I)/Segphos complex to give ortho-functionalized aryl ketones in high yields.本研究证实，阳离子铑(I)/H8-BINAP配合物可催化活化与未活化羰基化合物与1,6-二炔的[2+2+2]环加成反应，以高产率生成二烯酮。另一方面，在阳离子铑(I)/Segphos配合物存在下，未活化芳基酮可与1,6-二炔反应，高产率得到邻位官能化芳基酮。
