MnIV(salpn)Cl2 regioselectively trans-halogenates alkenes in a reaction for which the Mn-containing product is also identified; this is the first Mn-based halogenating system for which the reactive and final Mn-containing products are structurally characterized.

chlorine addition with polyaryliododichloride to cis or trans-1-phenylpropene is very similar to that observed in the reaction with Cl2 under ionic conditions, and its reactivity differs markedly from (dichloroiodo)benzene, which reacts via radical intermediates. Similar studies with 1-phenylalkynes and norbornene are described.

formed during ring-openingpolymerization of norbornene in benzene solvent using several unicomponent metal halide catalysts (W, Mo, Re, Ru, Os and Ir) were extensively investigated. Dimers and trimers were observed in all cases but were only substantial relative to polymer yields for WCl6 and ReCl5. The rate of formation of the dimers exactly paralleled that of the ring-openedpolymer, in marked contrast
