Aminocarbonylation of Aryl Tosylates to Carboxamides
摘要:
The palladium - catalyzed aminocarbonylation of aryl tosylates with amines is reported. Suitable conditions were identified by high throughput reaction screening and then further optimized. The substrate scope of the reaction with respect to the aryl tosylate component and the amine component are reported. Competitive aminolysis of the aryl tosylates to afford the amine toluenesulfonamides and the phenol was not observed.
micro–mesoporous structure composed of highly crystalline particle assemblies with sizes of 400–900 nm. The H-form Y-NA (HY-NA) is strongly acidic, and exhibits a good catalytic performance in the Ritterreaction, as compared with the H-form microporous zeolite Y and mesoporous zeolite ZSM-5.
The photochemical metal‐free carboamidation of aryl radicals has been exploited for the preparation of aromatic amides, including hetero‐ and polyaromatic derivatives, under visible light irradiation of arylazo sulfones in the presence of isocyanides in aqueous acetonitrile. The process was useful for the smooth preparation of the antidepressant moclobemide.

simple filtration process and recycled further for up to four consecutive recycle without any loss of activity and selectivity. The protocol is advantageous due to the ease in handling of the catalyst, simple workup procedure, phosphine-free, and effective catalyst recyclability.
