Microwave assisted efficient aminocarbonylation of N-tosylhydrazones with molybdenum hexacarbonyl and amines
摘要:
An efficient aminocarbonylation of N-tosylhydrazones derived from aromatic aldehydes and ketones mediated by molybdenum hexacarbonyl is reported. This method is palladium-free and provides a rapid access to the alpha-aryl acetamides in moderate to good yields. (C) 2013 Elsevier Ltd. All rights reserved.

To date, the N‐alkylation of amides with alcohols has not been studied with non‐noble metal base heterogeneous catalyst. Herein, a range of amide was efficiently N‐alkylated with various alcohols using cheap and easy to handle Ni/SiO2‐Al2O3.
迄今为止,尚未使用非贵金属碱多相催化剂研究酰胺与醇的N-烷基化。在此,使用廉价且易于处理的Ni / SiO 2 -Al 2 O 3将各种酰胺有效地与各种醇进行N-烷基化。

carboxylic acid and aminederivatives catalyzed by TiCp2Cl2. Arylacetic acid derivatives reacted with different amines to afford the corresponding amides in good to excellent yield except of aniline. Aryl formic acids failed to react with aniline but smoothly reacted with aliphatic amines and benzylamine in moderate to good yield, fatty acids reacting with benzyl and aliphatic amines give amides in good
