摘要：

The development of efficient catalysts for the alkylation of amines with carboxylic acids is attracting much attention. Herein, we would like to report an earth-abundant iron-catalyzed protocol for the N-alkylation of anilines using carboxylic acid as alkyl source and phenylsilane as reducing agent. With Fe-2(CO)(9) as a catalyst, a broad range of primary and secondary anilines are successfully converted to the corresponding tertiary anilines. Furthermore, this N-alkylation mainly goes through the amide pathway; while the aldehyde pathway can not be ruled out.
