A general copper/air catalytic system for selectively oxidative C-C bond cleavage of 1,2-diarylethan-1-one has been developed, giving aromatic aldehydes and N-benzoylation products of various amines in moderate to excellent yields. This research provides an alternative approach for the N-benzoylation of amine in mild and neutral conditions.
A palladium-catalyzed one-pot method for the synthesis of quinolines from commercial or readily available 2-amino aromatic ketones and alkynes is reported for the first time. This transformation offers an alternative method for the synthesis of polysubstituted quinoline.
Copper-Catalyzed N-Benzoylation of Amines via Aerobic C-C Bond Cleavage. -1,2-Diarylethanones suffer -CO-CH2-bond scission under aerobic conditions in the presence of CuCl 2 as catalyst enabling the formation of amides with a broad variety of aryl-, hetaryl-, and (di)alkylamines in modest to high yields. -(FAN, W.; YANG, Y.; LEI, J.; JIANG, Q.; ZHOU*, W.; J.

Palladium-Catalyzed Synthesis of Polysubstituted Quinolines from 2-Amino Aromatic Ketones and Alkynes. -PdBr 2-catalyzed one-pot method for the synthesis of quinolines from 2-amino aromatic ketones and alkynes is firstly reported. This new transformation offers an alternative method for the synthesis of polysubstituted quinoline derivatives. -(ZHOU*, W.; LEI, J.; Chem. Commun.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
