摘要

Abstract A highly efficient one-pot synthesis of carbazoles via palladium-catalyzed double N- arylation of primary amines with 2, 2′-dihalobiphenyls is described using a catalyst system comprised of tris (dibenzylideneacetone) dipalladium (0)(Pd 2 dba 3) and the proazaphosphatrane P (i-BuNCH 2 CH 2) 3 N (8) or its derivative (t-Bu) 2 P [DOUBLE BOND] N [BOND] P (i-BuNCH 2 CH 2) 3 N (9a) as the ligand. The process is effective for ...
