Kinetics of reactions between N-substituted tricyanovinylamines and thiols, where primarily reduction of the C=C double bond takes place, was investigated under conditions adequate to physiological ones. The reaction rates did not depend either on the type of the reacting thiol, or on the pH of the medium, but they decreased with the increasing pKa value of the imino group. A quantitative conversion of the thiol peptide glutathione to its oxidized form was evidenced.

The syntheses and properties of cationic nickel complexes containing dithio-β-diketonate and chelating bisphosphine ligands of general formula [Ni{R1C(S)CR2C(S)R3}{(PL1L2)R(PL3L4)}]X(Rj,Lj = alkyl or aryl, R = (CH2)n, n = 1-4, X = halide, BPh4, PF6, etc.) are described. The compounds are shown to be effective catalysts for the oligomerization and double bond shift isomerization of olefins with a high specificity for dimeric products rich in desirable linear and near linear isomers.
