- W4234898045 abstract "Substituent effects in the gas-phase pyrolysis of 1-arylethyl acetates (a reaction which proceeds via a transition state of carbonium ion character) are compared with those obtained in condensed-phase electrophilic aromatic substitutions and related reactions, and are found to closely parallel them. The p-methyl and p-t-butyl substituents activate in the inductive order, disproving the contention that the Baker-Nathan effect is primarily a function of the resonance requirement of a particular reaction. It is shown that the variable reactivity of the para-position in biphenyl in electrophilic and related reactions is unlikely to be attributable to an energy barrier restricting the attainment of a coplanar form, and that the electrophilic reactivity of the 2-position in fluorene cannot be satisfactorily represented by a single substituent constant. Sigma values in reactions proceeding via electron deficient centres are revealed as being partially dependent upon the extent of solvation though this effect is relatively minor. The pyrolysis reaction promises to be of fundamental value for examining the effects of substituents known to be strongly susceptible to solvent effects in condensed-phase reactions. Steric effects in the reaction are discussed." @default.
