One-pot stibine modified Co2(CO)8 catalyzed reductive N-alkylation of primary amides with carbonyl compounds
摘要:
A one-pot stibine modified Co-2(CO)(8) homogeneous catalytic reductive N-alkylation of primary amides using aldehydes/ketones as alkylating agents, is reported. Good to excellent yields of a wide range of secondary amides are obtained (up to 97%) under relative mild conditions. (C) 2012 Elsevier Ltd. All rights reserved.

Abstract Reaction of either benzyl chlorides or benzyl methyl ethers with hydrated ferric chloride in acetonitrile results in smooth Ritter reaction and formation of N-benzylacetamides in excellent yield.
excellent linear correlations with slopes of near unity. The results support the occurrence of path bifurcation after the rate-determining TS of the Beckmann rearrangement/fragmentation reaction, which has previously been proposed on the basis of molecular dynamics simulations. It was concluded that path-bifurcation phenomenon could be more common than thought and that a reactivity-selectivity argument based
