trans-Spanning ferrocene amidodiphosphine ligand: Synthesis, palladium complexes and catalytic use in Suzuki-Miyaura cross-coupling

Amide coupling between [2-(diphenylphosphino)phenyl]methylamine and 1′-(diphenylphosphino)ferrocene-1-carboxylic acid (Hdpf) afforded a novel diphosphine-amide, 1-{N-[(2-(diphenylphosphino)phenyl)methyl]carbamoyl}-1′-(diphenylphosphino)ferrocene (1), which was subsequently studied as a ligand for palladium(II) complexes. Depending on the metal precursor, the following complexes were isolated: [PdCl2(1-κ2P,P′)] (2), [PdCl(Me)(1-κ2P,P′)] (3), [(μ-1){PdCl2(PBu3)}2] (4) and [(μ-1){PdCl(LNC)}2] (LNC = 2-[(dimethylamino-κN)methyl]phenyl-κC1), featuring this ligand either as a trans-chelating or as a P,P′-bridging donor. The crystal structure of 2·1.25CH2Cl2 was established by X-ray crystallography, corroborating that 1 coordinates as a trans-spanning diphosphine without any significant distortion to the coordination sphere. Complex 2 together with a catalyst prepared in situ from 1 and palladium(II) acetate were tested in Suzuki-Miyaura reaction of aryl bromides with phenylboronic acid in dioxane.

Reactivity of di(azido)bis(phosphine) complexes of Ni(II), Pd(II) and Pt(II) toward organic isothiocyanates: Synthesis, structures, and properties of bis(tetrazole-thiolato) and bis(isothiocyanato) complexes

Di(azido)bis(phosphine) complexes of Group 10 metals {M(N3)2(PR3)2} underwent substitution with trimethylsilyl isothiocyanate (Me3Si-NCS) to give the corresponding bis(isothiocyanato) complexes, M(NCS)2L2 (M = Pd, L = PMe3 (1), PEt3 (2), PMe2Ph (3); M = Ni, L = PMe3 (4); M = Pt, L = PEt3 (5)), in which the isothiocyanato ligand is N-bound to the metal. By contrast, the bis(azido) complexes of Pd(II) and Pt(II) underwent 1,3-cycloaddition with organic isothiocyanates (R-NCS) to give tetrazole-containing thiolato complexes, M{S[CN4(R)]}2L2 (M = Pd, L = PMe3, R = allyl (6), benzyl (7), ethyl (8), phenyl (9), 2,6-dimethylphenyl (10); L = PMe2Ph, R = phenyl (11); L = PEt3, R = 2,6-dimethylphenyl (12); M = Pt, L = PMe3, R = Ph (13), Et (14); L = PEt3, R = Ph (15)). The chelating phosphine analogues, M{S[CN4(R)]}2L2 (L-L = depe (1,2-bis(diethylphosphino)ethane): R = Ph, M = Pd (16), Pt (17); R = 2,6-dimethylphenyl, M = Pt (18)) could also be obtained. Molecular structures of 6, 9, 14 and 18 clearly show the S-coordination of the thiolato ligands in these complexes. Treatments of tetrazole-thiolate complexes with benzoyl halide derivatives afforded various organic sulfides.
