PRIORITY: FR 85-7696 22 May 1985. 446-66-2 which is the cas registry number is also used here. DOCUMENT TYPE: Patent CA Section: 21 (General Organic Chemistry) The title compds. are prepd. by perfluoroalkylation of carbonyl compds. in an aprotic polar solvent in the presence of zinc. Thus, a pyridine soln. contg. 10mL PhCHO and 6.5 g Zn was treated with BrCF3 over 1 h while maintaining a BrCF3 pressure of between 1.5 and 3 bar. The resultant mixt. was hydrolyzed and unreacted PhCHO was removed to give 52% 1-phenyl-2,2,2-trifluoroethanol. .
