The gas-phase electrophilic attack by alkylating ions on benzocycloalkenes, involving interaction of isolated species, has shown a selectivity ratio conforming to the Mills-Nixon effect only for the first member of the series investigated in this study. Any positional selectivity diverging from that of o-xylene displayed by the higher homologues in electrophilic reactions run in solution thus appears to reflect specific medium effects.

Abstract
The gas-phase electrophilic attack by alkylating ions on benzocycloalkenes, involving interaction of isolated species, has shown a selectivity ratio conforming to the Mills-Nixon effect only for the first member of the series investigated in this study. Any positional selectivity diverging from that of o-xylene displayed by the higher homologues in electrophilic reactions run in solution thus appears to reflect specific medium effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
