Abstract

A method for the transition-metal-free direct C–H arylation of unactivated arenes is developed with aryl bromides as substrates and 8-hydroxyquinoline as an efficient promoter. A variety of biaryl compounds with structural diversity are obtained in moderate to high yields. Mechanistic studies reveal that the reaction proceeds via a homolytic­ aromatic substitution pathway.

Abstract

An efficient aza-Michael addition of azole to nitroalkene has been developed. In this conjugate addition, no catalyst was em-ployed and azole reacted with nitroolefin smoothly to afford new C-N bond adducts in good to excellent yields. [ABSTRACT FROM AUTHOR]
