Organoaluminum-promoted single homologation or ring expansion of ketones and aldehydes with diazoalkanes has been described, and among various organoaluminum reagents, exceptionally bulky methylaluminum bis(2,6-di-tert-butyl-4-methylphenoxide) (MAD) is found to be highly effective for the selective homologation of various ketones and aldehydes.
介绍了一种利用重氮烷烃进行的酮和醛的一级同系化或环扩张反应,并发现,在多种有机铝试剂中,特别庞大的甲基铝双(2,6-二叔丁基-4-甲基苯氧化物)(MAD)对各种酮和醛的选择性同系化具有高度效果。
