Highly efficient vinylaromatics generation via iron-catalyzed sp3 C–H bond functionalization CDC reaction: a novel approach to preparing substituted benzo[α]phenazines
Cu(II)-catalyzed synthesis of quinoxalines from o-phenylenediamines and nitroolefins
摘要:
An easy and efficient copper-catalyzed reaction for the synthesis of quinoxalines from o-phenylenediamines and nitroolefins is developed. This reaction could proceed well without additional base and be applied to various available substrates with a one-step synthetic procedure in moderate to good yields. (c) 2012 Elsevier Ltd.

An iron-catalyzed benzylic vinylation was developed to transfer the carbon atom in the N,N-dimethyl moiety of N,N-dimethylacetamide (or N,N-dimethylformamide) to 2-methyl azaarenes to generate 2-vinyl azaarenes.
