The regiochemical behavior of cyclohexene oxides bearing a remote O-functionality was determined in the gas-phase in opening reactions with MeOH, using a gaseous acid (D3/+, C(n)H5/+, Me2F+) as the promoting agent. The results obtained indicate the incursion in the opening process in the gas phase of H+(or D+)-mediated chelated bidentate species completely absent in the corresponding reactions (methanolysis) carried out in the condensed phase.
