용도

It finds its use in other preparations of substituted benzophenones, for benzoylation of phenols under basic, phase-transfer conditions. D,D,D-Trichlorotoluene is an intermediate, used exclusively in the industrial production of other intermediates such as Benzoylchloride, Benzotrifluoride and 2,4-Dihydroxybenzophenone. α,α,α-Trichlorotoluene is also used in determination of chlorinated toluenes in effluents of wastewater treatment plants and textile industries by closed loop stripping analysis.

In the presence of AlCl3, generates the exceptionally stable phenyldichlorocarbenium ion, useful in Friedel-Crafts acylations of otherwise unreactive systems. Thus, acetanilide, benzoylated in quantitative yield, whereas benzoyl chloride is ineffective: J. Am. Chem. Soc., 111, 7659 (1989).
