Homogeneous catalysis of olefin isomerisation. Part II. (a) Isomerisation of pent-1-ene catalysed by hydridochlorotris(triphenylphosphine)-ruthenium(II) in benzene; and (b) a novel procedure for evaluating velocity constants for a network of three first-order reversible reactions

The kinetic parameters for the polymerisation reaction of norbornene with RuCl3•3H2O, and RuCl2(PΦ3)3 using homogeneous catalysis have been determined (first-order with respect to two initiators, zero-order with respect to the monomer with RuCl3•3H2O, and variable order with RuCl2(PΦ3)3: Ea 6.2 kcal/mol for RuCl2(PΦ3)3 and 22.8 for RuCl3•3H2O) and leads us to propose different reaction mechanisms for the polymerisation starting from the two initiators, at least for the initiation step. With RuCl2(PΦ3)3 the slow step of the reaction is the metathesis whereas with RuCl3•3H2O the slow step is a ligand exchange at the initiator involving solvent (alcohol) by a dissociative or associative mechanism. This slow step is confirmed by a study of varying alcohol concentration and initiator aging. [Journal translation]

Decomposition Of Nitrous Oxide

It was recently discovered that iodine exerts a pronounced catalytic influence on the thermal decomposition of nitrous oxide. Bromine and chlorine have now been found to have similar effects. The reactions are of the first order with respect to the nitrous oxide and there appears to be little doubt that decomposition into a nitrogen molecule and an oxygen atom occurs under the influence of the halogen. The balance of evidence is in favour of the hypothesis that the effective catalyst is the free halogen atom. Whether the oxygen atom from the nitrous oxide remains attached to the halogen for a finite time cannot be definitely stated.

First Time

Manganese(II)-catalysed acid bromate oxidation of acrylic trans-crotonic and trans-cinnamic acids, in the presence of mercury(II), a bromide ion scavenger, exhibits first order in concentration of bromate, and reaches an upper limit with increase in substrate as well as catalyst concentration. Oxidation rate increases with acidity and is not altered when deuterium replaces either α or β proton of the olefinic acid. The catalytic effect of Mn(II) is displayed by its complex forming ability and the proposed mechanism assumes the oxidation of the formed Mn(II)-substrate π complex to Mn(III)-substrate π complex by acid bromate which further converts to products. The formation of a π complex between Mn(II) and the olefinic bond of the substrate is assumed for the first time.
