One-Pot Direct Synthesis of Weinreb Amides from Aryl and Hetero Aryl Halides Using Co2(CO)8 as an Effective CO Source Under Conventional Thermal Heating
摘要:
A successful protocol for the synthesis of Weinreb amides directly from aryl halides via aminocarbonylation with N,O-dimethyl hydroxylamine using Co-2(CO)(8) as an in situ CO source has been demonstrated. The effects of various reaction parameters such as temperature, base, and CO source have also been investigated and optimized.
