Fu, Wai Chung published the artcileA benzo[c]carbazolyl-based phosphine ligand for Pd-catalyzed tetra-ortho-substituted biaryl syntheses, Category: naphthyridine, the publication is Organic Chemistry Frontiers (2016), 3(2), 273-276, database is CAplus.
A new benzo[c]carbazolyl-based phosphine ligand I has been designed and synthesized. This newly developed ligand I efficiently facilitates the Pd-catalyzed syntheses of tetra-ortho-substituted biaryl compounds RR1 [R = C6F5, 2,3-dimethoxynaphthalen-1-yl, dimethyl-1,2-oxazol-4-yl, etc.; R1 = 2,6-(CH3)2C6H3, 2,6-(CH3O)2C6H3, 2,4,6-(CH3)3C6H2, 2,6-(CH3)2-4-H3COC6H2, 2-methoxynaphthalen-1-yl] via Suzuki-Miyaura cross-coupling. With 1 mol% of the Pd(OAc)2/I catalyst, sterically congested biaryls were afforded in good-to-excellent yields. In particular, the mild reaction conditions exhibited good compatibility of heterocycles and functional groups including esters and nitrile. The ligand I was structurally characterized by X-ray crystallog. anal.
