Photolysis of the title bis-diazirine matrix-isolated in Ar at 10 K monitored by IR and UV/vis spectroscopy indicated that the diazirine underwent stepwise elimination of N2 to produce 3-(4-chlorocarbenophenyl)-3-chlorodiazirine which then eliminated the

Process for preparing hydroxylated aromatic compounds

A process for preparing hydroxylated aromatic compounds optionally bearing at least one trifluoromethyl, trifluoromethoxy or trifluoromethylthio group. A chloroformate or fluoroformate, optionally bearing at least one trihalomethyl-, trihalomethoxy- or trihalomethylthiophenyl group, is reacted with liquid hydrofluoric acid. The aromatic compounds obtained are useful as synthesis intermediates in the pharmaceutical or the plant-protection industry.
