General description

2,6-Difluorotoluene reacts with chlorine to give 2,6-difluorobenzyl chloride, which gets converted to 2,6-difluorobenzaldehyde through Sommelet′s reaction. Six-fold potential for internal methyl rotation in first singlet excited state and cation ground state of 2,6-difluorotoluene has been determined.

Application

2,6-Difluorotoluene was used to generate jet-cooled 2,6-difluorobenzyl radical and to investigate its vibronically resolved emission spectra.
