The anion of complex 6, shows strong O-Hpi(C?C) interactions and weaker C-Clpi(C?C) contacts between the protons of two water and two CH2Cl2 molecules and the CalphaCbeta of mutually cis alkynyl groups. In this complex the presence of additional O-HH-C(Cp) and C-ClH-C(Cp) contacts gives rise to an extended bidimensional network. The optical and electrochemical properties of all derivatives have been examined. It is remarkable that for complexes 2 and 5 a facile oxidatively induced coupling, giving rise to 1,4-diferrocenylbutadiyne, is observed, this also having been proven by chemical oxidation.

Mechanistic studies of the amination of aryl bromides catalyzed by palladium complexes containing the chelating phosphines BINAP and DPPF are reported. The coupling of primary alkyl- and arylamines, secondary cyclic alkylamines, and secondary arylalkylamines with bromoarenes in the presence of stoichiometric base and Pd(BINAP)2 (1a) as catalyst, and the reaction of aniline with 4-Br-C6H4-t-Bu in the presence of base catalyzed by Pd(DPPF)2 (2), were studied. The stoichiometric oxidative additions of PhBr to 1a and to 2 were turnover limiting, and kinetic studies were also conducted on this individual step. The stoichiometric oxidative addition of PhBr to 1a showed an inverse first-order dependence on added ligand when the PhBr concentration was low but depended solely on the rate of chelating ligand dissociation at high [PhBr]. There was no measurable solvent effect. In addition, the rates were indistinguishable in the presence and in the absence of amines and salts that are present in the catalytic amination reactions. Similar qualitative data for the oxidative addition of PhBr to 2 was obtained by 1H NMR spectroscopy. The observed rate constants for the overall amination reactions catalyzed by 1a were shown to be zero order in aryl halide, amine, base, and added ligand, while they were first order in catalyst. These data indicated that the kinetic behavior of the overall reaction was dictated solely by the rate of ligand dissociation from 1a, as observed for the oxidative addition. When secondary amines were used, deviation from this behavior was observed. This anomalous behavior resulted from decay of catalyst rather than a change in the turnover-limiting step. A catalyst decomposition pathway that involves backbone P-C bond cleavage of the chelating bisphosphine ligands was revealed by the stoichiometric oxidative addition studies. Quantitative rate data were also obtained for reaction of 4-Br-C6H4-t-Bu with aniline in the presence of base catalyzed by 2. The observed rate constants were zero order in amine and base, inverse first order in added ligand, and first order in aryl bromide. At low concentration of added ligand, the reaction appeared to be first order in amine. However, this deviation from the expected behavior was due to reversible reaction of the catalyst with product.

The Lewis acid tris(pentafluorophenyl)borane was found to rapidly promote ring-opening beta-hydride elimination in a 1,1?-bis(diphenylphosphino) ferrocene (dppf) nickelalactone complex under ambient conditions. The thermodynamic product of nickelalactone ring-opening was characterized as (dppf)Ni(CH(CH3)CO2BArf3), the result of beta-hydride elimination and subsequent 2,1-insertion from a transient nickel(II) acrylate hydride intermediate. Treatment of (dppf)Ni(CH(CH3)CO2BArf3) with a nitrogen-containing base afforded a diphosphine nickel(0) eta2- acryl borate adduct. Formation of the diphosphine nickel(0) eta2- acryl borate adduct completes a net conversion of nickelalactone to acrylate species, a significant obstacle to catalytic acrylate production from CO 2 and ethylene. Displacement of the eta2-acrylate fragment from the nickel center was accomplished by addition of ethylene to yield a free acrylate salt and (dppf)Ni(CH2CH2).

Reaction of Mo(CO)3(CH3CN)3 with an equimolar amount of 1,1?-bis(diphenylphosphino)-ferrocene (dppf) in refluxing acetonitrile gives rise to fac-Mo(CO)3(dppf)(CH3CN) (1) in 51% yield. While 1 reacts with [60]fullerene in chlorobenzene at about 90C to produce an isomeric mixture of fac/mer-Mo(CO)3(dppf)(eta2-C60) (2) in 21% yield, the photolysis of Mo(CO)4(dppf) and [60]fullerene in chlorobenzene at ambient temperature affords 2 in 87% yield. Similarly, mer-W(CO)3(dppf)(eta2-C60) (3), [mer-W(CO)3(dppf)]2(eta2,eta2-C60) (4), mer-W(CO)3(dppf) (eta2-C70) (5), and [mer-W(CO)3 (dppf)]2(eta2,eta2-C70) (6) can be prepared by photolysis of W(CO)4(dppf) with [60]- or [70]fullerene in 87%, 13%, 51%, and 48% yields, respectively. While all the new compounds 1-6 have been characterized by elemental analyses and spectroscopic techniques, the structures of 1, W(CO)4(dppf), and 3 have been confirmed by single-crystal X-ray diffraction analyses. The cyclic voltammetric responses of 2 and 3 show that their sequential fullerene-centered reductions are shifted toward more negative potential values by about 0.2 V with respect to those of free C60. Such a negative shift is quite similar to that previously observed for the related complexes W(CO)3(dppb)(eta2-C60) and Mo(CO)3(dppe)(eta2-C60). Moreover, the fullerene-centered reductions of 5 are negatively shifted by about 0.1 V with respect to free C70, thus supporting that the eta2-coordination of the W(CO)3(dppf) fragment to fullerenes causes a higher electronic interaction with C60 than with C70.

High-pressure nuclear magnetic resonance and infrared study of the hydroformylation of 1-hexene in the presence of rhodium(1) complexes acting as catalysts was presented. The catalysts exhibited good activity and moderate regioselectivity. It was found that the formation of kinetic dicarbonyl products at room temperature took place, irrespective of the rhodium precursor. Square-planar dicarbonyl complexes containing two cis carbonyl groups were also obtained.
