The addition of lithium chloride (LiCl) to a solution of polystyryllithium (PStLi) in tetrahydropyran (THP) reduces the rate of propagation of PStLi at a low concentration of the latter but accelerates it at higher concentrations of PStLi. Moreover,

Experiments by Maerker et al.1 in 1998 showed that the conversion of the dilithium adduct of diphenyl acetylene, (Z)-2, to its trans derivative (E)-5 occurred at a rate that was independent of time, leading them to propose a model for this reaction.

Reaction of the two-electron donor K+Crown K- with phenylacetyl peroxide produces phenylacetic acid, toluene, bibenzyl, and benzyl phenylacetate. The formation of products derived from benzyl radical shows that some electron transfers must be stepwis

The principle of the electron photoejection technique is explained. This approach leads to the formation of transient spectra of unstable intermediates, allowing their recording and providing their extinction coefficients. Moreover, it permits determ

The story of the discovery of living polymers is presented. Living polymers are polymers that retain their ability to propagate and grow to a desired size while their degree of termination or chain transfer is still negligible. Theoretical and mechan

Dynamic reversible equilibria established between unimeric alcohol molecules and linear open chains formed by linking the unimers through H-bonding were discussed in numerous papers summarized in Journal of Molecular Liquids, 1995, 64, 283. Confusion

Some problems in ionic polymerization are reviewed. The existence of a variety of species participating in ionic polymerizations is stressed and the distinction between the growing, dormant, and dead polymers emphasized. An example of a kind of polym
