Preparation of 7-alkylcyclohepta-1,3,5-trienes from organometallics and either tropylium tetrafluoroborate or 7-ethoxycyclohepta-1,3,5-triene

The reaction of several organolithium compounds and the reaction of α-unsaturated organozinc and organoaluminium compounds with either the readily prepared tropylium tetrafluoroborate or with 7-ethoxycyclohepta-1,3,5-triene give the corresponding 7-alkylcyclohepta-1,3,5-trienes.On the other hand, with organomagnesium compounds, only 7-ethoxycyclohepta-1,3,5-triene gives the expected 7-alkylcyclohepta-1,3,5-trienes while the reaction of tropylium tetrafluoroborate is abnormal.

Matrix photoionization experiments have been performed for several p-dialkylbenzenes and alkylcycloheptatrienes.Broad absorptions at 23500 and 34700 cm-1 following UV matrix two-photon ionization of p-xylene are assigned to the parent cation, in agreement with photodissociation spectra of gaseous cation.A broad absorption at 20240 cm-1 following vacuum-UV matrix photoionization of 7-methylcycloheptatriene is assigned to the parent cation, in agreement with the difference between photoelectron bands.Mercury arc photolysis has been used to activate the extensive rearrangements of the p-xylene and 7-methylcycloheptatriene cations, which finally rearrange to a common conjugated triene cation identified as a substituted methylenecyclohexadiene cation.
