de Boer, Sandra Y. published the artcileCuI click catalysis with cooperative noninnocent pyridylphosphine ligands, Related Products of pyridine-derivatives, the publication is Inorganica Chimica Acta (2012), 336-342, database is CAplus.
The authors describe the synthesis and characterization of compound L1H, 2-di(tert-butyl)phosphinomethyl-6-methylpyridine (NPtBu), and the 1st dimeric CuI complex, [Cu(μ-Br)(L1H)]2 (3), with this novel bidentate ligand. The mol. structure of 3 was determined by x-ray crystallog. The ligand scaffold exhibits noninnocent reactivity through dearomatization behavior, similar to its well-studied tridentate analog L2H, 2,6-bis((di-tert-butylphosphino)methyl)pyridine (PNPtBu). The mol. structure of [Cu(CCPh)(L2H)]2 (4) is reported, which is a rare case of a crystallog. characterized Cu-acetylide dimer. Cu(I) complexes with either ligand L1H or L2H or their dearomatized counterparts act as active, cooperative catalysts for the [2+3] polar cycloaddition of azides and acetylenes. These results represent the 1st indications of selective Cu-based cooperative catalysis, using noninnocent lutidine-based PNP backbone. Catalysts [Cu(PN-PtBu)] (2, PN-PtBu = de-aromatized L2H (C6H3P(:CHPtBu2)-2-(CH2PtBu2)-6)) and [Cu(CCPh)(L2H)] (5) could thus be termed all-inclusive systems for this reaction.
