The amination of secondary alcohols to give tertiary amines in the presence of different in situ generated ruthenium catalysts has been investigated in detail. By applying a combination of [Ru3(CO)12] and N-phenyl-2-(dicyclohexylphosphanyl)pyrrole as the catalyst, cyclic amines can be alkylated with different alcohols in high yield, whereas aliphatic amines gave transalkylation side products.(© Wiley-VCH
已经详细研究了在不同的原位生成的钌催化剂存在下仲醇胺化生成叔胺的过程。通过使用 [Ru3(CO)12] 和 N-苯基-2-(二环己基膦酰基)吡咯的组合作为催化剂,环胺可以用不同的醇以高产率进行烷基化,而脂肪胺产生烷基转移副产物。(© Wiley -VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
