چکیده

A new indene-based ligand featuring pendant phosphine sulfide and amine donor fragments has been developed; Rh(I) coordinates to the neutral form of the ligand in a kappa2-[N,S] fashion, while the anionic form of the ligand binds Rh(I) and Mn(I) in kappa2-[C,S] and eta5 modes, respectively.

Rhodium(I) complexes of α-keto-stabilised 1,2-bis(diphenylphosphino)alkane mono ylides

Rhodium(I) complexes of the hybrid ylide-phosphine ligands, Ph2P(CH2)nPPh2(CHC(O)C6H5) (n = 1: dppm-yl, or 2: dppe-yl) have been synthesised from [Rh(μ-Cl)(COD)]2 (COD = 1,5-cyclooctadiene) and characterized by NMR spectroscopic and X-ray structural methods. The dppe-yl behaves as an ambidentate ligand; it functions as a monodentate P-donor ligand with a dangling ylidic carbon in the neutral ch...

Synthesis and structures of mononuclear 3,4-bis(trifluoromethyl)pyrrolyl complexes of Rh(I) and Ni(II).

New mononuclear complexes of the 3,4-bis(trifluoromethyl)pyrrolyl ligand (3,4-(CF3)2-Pyr(-)) with Rh(I) and Ni(II) are reported. Reaction of 3,4-(CF3)2-PyrNa with [Rh(COD)Cl]2 produces [Rh(PMe3)3(3,4-(CF3)2-Pyr)] (1) while reaction of 3,4-(CF3)2-PyrH with [Ni(PMe3)2Me2] (2) or [Ni(PMe3)2Ph2] (4) gives [trans-Ni(PMe3)2(3,4-(CF3)2-Pyr)(CH3)] (3) or [trans-Ni(PMe3)2(C6H5)(3,4-(CF3)2-Pyr)] (5) resp...
