The tris(acetylacetonato)rhodium(III) catalyst is shown to be a versatile catalyst in the presence of DABCO (1,4‐diazabicyclo[2.2.2]octane) as ligand for the α‐alkylation of ketones followed by transfer hydrogenation, for the one‐pot β‐alkylation of secondary alcohols with primary alcohols and for the alkylation of aromatic amines in the presence of an inorganic base in toluene.
在DABCO(1,4-二氮杂双环[2.2.2]辛烷)作为配体的α-烷基化酮,然后进行转移氢化的情况下,三(乙酰丙酮基)铑(III)催化剂是一种多功能催化剂。仲醇与伯醇的单锅β-烷基化反应,以及在甲苯中存在无机碱的情况下芳族胺的烷基化反应。
