, p. 77 - 88 (1991)
New data for the deuteroformylation of propene and hydroformylation of deuteropropenes are presented, together with revised data for the hydroformylation of but-1-ene-4-d3.The mechanism of formation of isomeric aldehydes is discussed, and it is concluded that several reaction paths may be followed depending on the reaction conditions and the structure of the substrate.

The Mo and V nitrogenases are structurally homologous yet catalytically distinct in their abilities to reduce CO to hydrocarbons. Here we report a comparative analysis of the CO-reducing activities of the Mo- and V-nitrogenase cofactors (i.e., the M and V clusters) upon insertion of the respective cofactor into the same, cofactor-deficient MoFe protein scaffold. Our data reveal a combined contribution from the protein environment and cofactor properties to the reactivity of nitrogenase toward CO, thus laying a foundation for further mechanistic investigation of the enzymatic CO reduction, while suggesting the potential of targeting both the protein scaffold and the cofactor species for nitrogenase-based applications in the future.

The thermal decomposition of pyrrolidine was studied behind reflected shocks in a single-pulse shock tube over the temperature range 900-1400 K and overall densities of ca. 3 x 1E-5 mol/cm3.Under these conditions the following reaction products were found in the postshock mixtures: H2, CH4, C2H4, C2H6, C2H2, C3H6, CH2=C=CH2, CH3CCH, CH2=CHCH2CH3, HCN, CH3CN, CH2=CHCN, C2H5CN, and small quantities of pyrrole and butadiene.Studies with a mixture of pyrrolidine and pyrrolidine-d9 show that C2H4 and C3H6 are produced by direct ring cleavage with the following rate parameters: pyrrolidine -> C2H4 + (CH2)2-NH, k = 3.42 x 1E16 exp(-75.2 x 1E3/RT) s-1 and pyrrolidine -> C3H6 + CH2=NH, k = 1.35 x 1E16 exp(-80.4 x 1E3/RT) s-1, where R is expressed in units of cal/(K mol).Hydrogen cyanide has the highest concentration among the nitrogen-containing products, followed by acetonitrile.No reaction products resulting from pyrrolidine isomerization were observed.
