摘要：

An effective synthesis of N,N-dimethylacetamide (DMAc) via NaCo(CO)(4)-catalyzed carbonylation of trimethylamine is reported. Lewis acid (AlCl3, FeCl3, BiCl3, InCl3 etc.) and (CH3)(4)NI were used as promoters to activate the unreactive sp(3) carbon-nitrogen (C-N) bond of trimethylamine and a significant increase in catalytic activity was observed. High selectivity (98%) and yield of DMAc (96%) were obtained under relatively mild reaction conditions. Based on the role of promoters and the products in the reaction, a plausible mechanism that contains two different ways of activating C-N bond was proposed. (C) 2013 Elsevier B.V.
