The reactions of (C9H7)Fe(CO)2R (R = CHMe2, Me) with phosphines and phosphites (L) yield two series of indenyl complexes (C9H7)Fe(CO(COR)(L) via the migratory insertion process.The acyl complexes provide a case of diastereotopic shielding by an asymmetric iron atom.The phosphorus ligands exert electronic effects on the terminal carbonyl group of the methyl complexes that are essentially the same in the indenyl system and in the analogous cyclopentadienyl system.Substitution of methyl for isopropyl in the acyl moiety increases ?-back bonding from iron to carbonyl.The structure of (C9H7)Fe(CO)(COCHMe2)(PPh3) has been determined by X-ray analysis, and exhibits a distorted eta5 coordination of the indenyl ligand .

Acylphosphines of the type (1-Ad)nP3-n (n=1,2; R=t-Bu, 1-Ad, Ph) were synthesized via the reaction of 1-AdPH2 or (1-Ad)2PH with the corresponding carboxylic acid chlorides/NEt3.The reaction of 1-AdPH2 with phtaloyl dichloride/NEt3 led to the five-membered heterocycle 4.In the case of n=1, R=1-Ad the monosubstitution product 1-AdP(H)C(:O)(1-Ad) 1b was also observed. 1-AdP(H)C(:O)Ph 1e was selectively formed when 1-AdPH2 was allowed to react with PhC(:O)Cl/K2CO3, whereas the remaining PH-proton in 1e could be substituted by C(:O)t-Bu in its reaction with t-BuC(:O)Cl/NEt3 to give 2d.The action of trifluoroacetic acid anhydride on 1-AdPH2 or (1-Ad)2PH led to the trifluoroacetyl phosphines 2c and 3c.The reaction of 1-AdP2 2a with aqueous H2O2 or elemental sulfur furnished the corresponding chalcogenides 5 and 6, with a large excess of methyl iodide <1-AdPMe3>I 7 was formed.The carbonyl complexes (L)M(CO)n (L=2a; M=Ni, n=3:8; M=Fe, n=4:9) were obtained upon reaction of 2a with Ni(CO)4 and Fe2(CO)9, respectively.Tris-1-adamantoylphosphine 10 was formed as a by-product in the reaction of P(SiMe3)3 with 1-AdC(:O)Cl and was converted to the chalcogenides <(1-AdC(:O)>3P(:X) (X=O: 13; X=S: 14).

Although 2-phenylpyridine (ppy)-type complexes have been employed very successfully for the design of luminescent IrIII and PtII complexes, corresponding d10-coinage metal complexes are unknown. We report on the synthesis of the first, room-temperature-stable, CuI ppy-type complexes, by C-H activation of 2-(2,3,4,5-tetrafluorophenyl)pyridine (Htfppy, 1) using [Cu(OH)(IDipp)] (2) (IDipp = bis(2,6-di-isopropylphenyl)imidazole-2-ylidene) or by lithiation of 1 and subsequent reaction with CuBr·SMe2 in the presence of a POP ligand (POP = bis{2-(diphenylphosphanyl)phenyl} ether) in THF, giving [Cu(tfppy)(IDipp)] (3) or [Cu(tfppy)(POP)] (4). The complexes thus obtained adopt distorted trigonal and tetrahedral coordination geometries, respectively. Gold(I) tfppy complexes with IDipp (5) or PTol3 (6) ligands have also been prepared, showing a preference for linear coordination environments due to the noncoordinating pyridine moiety of the tfppy ligand. These structural differences have a profound effect on the photophysical properties of the coinage metal ppy compounds. The CuI tfppy complexes exhibit intense orange-red luminescence (lambdamax = 610 (3), 607 (4) nm) from a 3(intraligand)CT state in the solid state at room temperature, with phosphorescence lifetimes of tau = 8.6 (3) and 9.5 (4) mus. In contrast, the linear coordination leads to weak emission of the AuI complexes, with 5 displaying simultaneous fluorescence and phosphorescence. Surprisingly, reaction of 2 with Htfppy (1) in MeCN leads to solvent activation and to isolation of a copper acetamide complex, [Cu(N(H)C(O)Me)(IDipp)] (14).

The structures of isomeric eta3-allyl palladium complexes, [Pd(eta3-1,3-R?2-C3H 3){kappa2-(racemic)-(C20H12O 2)PN(CHMe2)PY2}](PF6)(R? = Me or Ph; Y = C6H5 or OC6H5) have been elucidated by high field two-dimensional NMR spectroscopy. The solid state structure of [Pd(eta3-1,3-Ph2-C3H 3){kappa2-(racemic)-(C20H12O 2)PN(CHMe2)PPh2}](PF6) has been determined by X-ray crystallography. Preliminary investigations show that the diphosphazanes, 1 and 2 function as efficient auxiliary ligands for catalytic allylic alkylation but give rise to only moderate levels of enantiomeric excess.
