Reference of 4923-87-9, New research progress on 4923-87-9 in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. In a article, 4923-87-9, molcular formula is C8H5BrS, introducing its new discovery.
Direct arylation of cyclopentanones has been a long-standing challenge because of competitive self-aldol condensation and multiple arylations. Reported herein is a direct mono-alpha-C-H arylation of cyclopentanones with aryl bromides which is enabled by palladium/amine cooperative catalysis. This method is scalable and chemoselective with broad functional-group tolerance. Application to controlled sequential arylation of cyclopentanones has been also demonstrated. Be direct: A direct alpha-C-H arylation of normal cyclopentanones with aryl bromides, enabled by palladium/amine cooperative catalysis, features an exceptionally high selectivity for monoarylation, use of readily available starting materials, good scalability, and broad functional-group tolerance.
