Abstract

Abstract A green and efficient preparation of functionalized δ-carbolines/carbazoles via reductive ring closure by 1, 2-bis (dipenylphosphino) ethane under solvent-free conditions is described. The starting materials 3-nitro-2-phenylpyridines/2-nitrobiphenyl derivatives are readily prepared through Suzuki–Miyaura cross-coupling reaction from commercially available compounds. And the polar by-product ethane-1, 2-diylbis (diphenylphosphine ...
