Unexpected Cross-Coupling Reaction between o-Chloroaryl Ketones and Organomanganese Reagents
摘要:
Alkyl- and arylmanganese reagents react with o-chloro or o-bromoaryl ketones to give the substituted ketones in high yields. The cross-coupling reaction is performed under mild conditions (-60 to +40 degreesC, 30 min to 4 h) and takes place with excellent chemoselectivity.
