Rates and products of the reaction of a b,b-dichlorobenzylic alcohol and its derivatives in trifluoroacetic acid-sulfuric acid

Rates and products of the reaction of a b,b-dichlorobenzylic alcohol and its derivatives in trifluoroacetic acid-sulfuric acid. A 1,2-chlorine shift giving an a-chloro ketone. Jensen, Bruce L.; Peterson, Paul E.Several substances like 35996-56-6 may be metioned in this study. (Dep. 35996-56-6 is the cas registry number. This chemical is also mentioned in this article. Chem., Univ. Maine, Orono, Maine, USA). J. Org. Chem., 42(25), 4052-5 (English) 1977. CODEN: JOCEAH. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) O-ClC6H4CH(OR)CCl2Me (I; R = p-MeC6H4SO2, p-BrC6H4SO2) gives o-ClC6H4CHClAc and I (R = CF3CO) via chloronium intermediate II in CF3CO2H contg. H2SO4. The absence of leaving-group substituent effects on the rearrangement kinetics is assocd. with the acid catalysis of the rearrangement. ..
