• The possibility of releasing of trifluoroacetic acid from TiO(TFA)2 in protic solvents was ruled out since when TiO(02CCF3)2 was refluxed in methanol for 2 h, the quantitative yield of unchanged TiO(02CCF3)2 was obtained. In the case of TiCl3(OTf) with assumption of releasing of three molar equivalents of HC1 through its reaction with methanol, methanolysis of styrene oxide with 0.03 molar equivalents of hydrochloric acid was studied. In comparison with the reaction of styrene oxide with 0.01 molar equivalent of TiCl3(OTf), the reaction with hydrochloric acid was found to be five times slower
