Rhodium(III)-catalyzed enantioselective oxidative C-H/C-H cross-coupling reaction between two arenes is disclosed. With the combination of a chiral CpRh(III) complex and a chiral carboxylic acid additive, the direct coupling reactions between 1-aryl isoqu
Unexpected ortho-Heck Reaction under the Catellani Conditions

An unexpected ortho-Heck reaction has been discovered during the study of palladium/norbornene (Pd/NBE) catalysis. Under the Catellani reaction conditions in the presence of lithium salts and olefins, Heck coupling takes place at the ortho position instead of the commonly observed ipso position; meanwhile, a norbornyl group is introduced at the arene ipso position. Systematic deuterium labeling and crossover experiments suggest an unusual 1,4-palladium migration/intramolecular hydrogen transfer pathway. The knowledge gained in this study could provide insights for the future development of the Pd/NBE catalysis.
Copper-Catalyzed Dehydrogenative Formal [4 + 2] and [3 + 2] Cycloadditions of Methylnaphthalenes and Electron-Deficient Alkenes

Higher π-extended naphthalene, contained in methylnaphthalenes, which could capture alkyl radicals via SOMO-LUMO interactions, enabled the development of Cu-catalyzed formal [4 + 2] and [3 + 2] cycloadditions between methylnaphthalenes and electron-deficient alkenes. Under copper catalysis, a series of electron-deficient alkenes and methylnaphthalenes with different substituents were successfully incorporated with di-tert-butyl peroxide (TBP) as an oxidant and radical initiator, providing a wide range of cycloadducts.
