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.
