Ziegler‐Natta polymerization of 1‐alkenes: relative reactivities of some monomers toward insertion into metal‐methyl bonds

AbstractThe relative reactivities of ethylene, 1‐butene and 3‐methyl‐1‐butene in the insertion reaction into the metal‐methyl bond of the active site of the catalytic system δ‐TiCl3/Al(13CH3)3/Zn(13CH3)2 are determined by 13C NMR end groups analysis. The relative reactivities of propene, 3‐methyl‐1‐pentene and 3‐ethyl‐1‐pentene are also calculated from previous data. Some correlations between relative reactivities and reaction mechanism are proposed.

Photogeneration of reactive titanium and zirconium species: a CIDNP study

Chemically induced dynamic nuclear polarization (CIDNP) studies of the photolytically initiated reactions of Cp′ 2Ti(CH 3) 2 (Cp′ = methylcyclopentadienyl) and Cp 2Zr(CH 3) 2 (Cp = cyclopentadienyl) have revealed that homolysis of the metalmethyl bond takes place, followed by a rapid recombination. The metal radical is shown to be one of the patterns in the polarizing radical pair. Only very fast scavengers such as nitroxides, dioxygen and thiophenol can compete with the recombination reaction. Dimethylzirconocene undergoes a photochemically-initiated ethylene insertion reaction in which the olefin is inserted into the zirconiummethyl bond via an unprecedented radical process.
