All polymerization reactions are categorized into two large different families, chain- and step-growth polymerizations, which are typically incompatible. Here, we report the simultaneous chain- and step-growth polymerization via the metal-catalyzed radical copolymerization of conjugated vinyl monomers and designed monomers possessing unconjugated C – C and active C-Cl bonds. Especially, almost ideal linear random copolymers containing both vinyl polymer and polyester units in a single polymer chain were formed by the CuCl/1,1,4,7,10,10-hexamethyltriethylenetetramine- or RuCp*Cl(PPh 3)2-catalyzed copolymerization of methyl acrylate (MA) for the chain-growth polymerization and 3-butenyl 2-chloropropionate (1) for the step-growth polymerization. In contrast, other transition metal catalysts, such as CuCl with tris[2-(dimethylamino)ethyl]amine or N,N,N?,N?, N?-pentamethyldiethylenetriamine and FeCl2/PnBu3, resulted in branched structures via the concomitant chain-growth copolymerization of 1 with MA. The polymerization mechanism was studied in detail by NMR and MALDI-TOF-MS analyses of the polymerizations as well as the model reactions. Furthermore, a series of copolymers changing from random to multiblock polymer structures were obtained by varying the feed ratios of the two monomers. These copolymers can be easily degraded into lower molecular weight oligomers or polymers via methanolysis of the ester-linkages in the main chain using sodium carbonate.

A full account of the catalysis of hydrosilylation of the C=C bond in olefins, their derivatives with functional groups as well as in vinyl-trisubstituted silanes by ruthenium(II) and ruthenium(III) phosphine precursors is given.The ruthenium complexes are far more efficient catalysts for the hydrosilylation of 1-alkenes and vinyl-substituted silanes than for the substituted olefins and unsaturated esters.General features characterizing all hydrosilylation reactions catalyzed by the above catalysts are as follows: the reaction proceeds with alkoxy-substituted silanes(also with vinylsilanes) in the absence of solvent, and is enhanced (for RuII and olefins occurs exclusively) in the presence of molecular oxygen.Two general mechanisms are proposed for hydrosilylation of olefins and of vinylsilanes, respectively, which account for most of the experimental observations.

Halogen complexes of ruthenium cyclopentadienyl [CpRu (PTA)2 X]; [CpRu (PTA) (PPh3) X]; [CpRu (PPh3) 2 Cl], and [CpRu (mPTA) (PPh3) X]+ (Cp= C5 H5; PTA=1,3,5-triaza-7-phosphaadamantane; mPTA+ = [1-methyl-1,3,5-triaza-7- phosphaadamantane]+; X= Cl-, I-) were investigated by electrospray mass spectrometry (ESI-MS), in flow-cell cyclic voltammetry, by microelectrodes, and by combined online electrochemistry and electrospray mass spectrometry (EC/ESI-MS) in dimethyl formamide solution. Coordination changes and the structures of the initial compounds and the products of the electro-oxidation of the Ru(II) complexes were traced by in situ EC MSn experiments which revealed their fragmentation pathways. ESI-MS collision-induced dissociation fragmentations of the initial reactants and the oxidation products were explained by soft acid-hard base considerations taking into account the different nature of Ru(II)-Ru(IV) centers. The electrochemical studies show that it is possible to tune the formal potentials for the oxidation of [CpRu L2 X] complexes by over 300 mV by proper selection of the ligands. The increase of the redox potential by the different ligands follows the order PTA< PPh3 < mPTA+. We demonstrate a similarity between the propensity of the ligand to fragment out in the gas phase and its relationship to the formal potential of the complex.

The complexes Ru(4,4?-C ? CC6H4C6H4NO2)(PPh3)2(eta-C5H5) and Ru(4,4?-C ? CC6H4C ? CC6H4NO2)(PPh3)2(eta-C5H5) have been prepared and the latter structurally characterized; they belong to a series of organometallic donor-bridge-acceptor compounds containing (cyclopentadienyl)bis(phosphine)ruthenium(II) centres as donors, conjugated arylacetylide bridges, and nitro acceptor groups. Electrochemical data for the series of complexes Ru(C ? CR)(PR?3)2(eta-C5H5) (R=Ph, 4-C6H4NO2, R?=Ph, Me; R=4,4?-C6H4C6H4NO2, (E)-4,4?-C6H4CH=CHC6H4NO2, 4,4?-C6H4C ? CC6H4NO2, 4,4?-C6H4N=CHC6H4NO2, R?=Ph) are consistent with an RuII/III couple whose oxidation potentials vary strongly with chain-lengthening from one-ring to two-ring acetylide ligand, but show little variation with changes at the bridging unit of the two-ring acetylide ligand. The molecular quadratic and cubic optical nonlinearities of the series of complexes have been determined by hyper-Rayleigh scattering (HRS) and Z-scan techniques, respectively. Molecular first hyperpolarizabilities by HRS at 1064 nm are dispersively enhanced; experimental and two-level corrected data suggest an increase in nonlinearity on chain-lengthening of the bridge, in proceeding from C6H4 to C6H4C6H4 and then C6H4C ? CC6H4 and C6H4CH=CHC6H4, a general trend that is reproduced by semiempirical ZINDO computations. Cubic hyperpolarizabilities by Z-scan at 800 nm are negative for complexes with nitro acceptor groups, probably a result of two-photon dispersion, with absolute values (up to 850 × 10-36 esu) large for small organometallic complexes; as with quadratic nonlinearities, cubic nonlinearities increase substantially on bridge lengthening, with little variation on phosphine substitution.
