DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Mechanism of naphthalene (c-C10H8) formation by the recombination of cyclopentadienyl radicals (c-C5H5) was investigated by monitoring the time profiles of H atom behind the reflected shock of trifluoromethoxybenzene (C6H5OCF3) highly dild. with Ar. The rate const. for c-C5H5 + c-C5H5 ? c-C10H8 + 2H was detd. to be 3. 91-20-3 and 456-55-3 are just another two chemicals used in this study.3 ′ 1017 exp(-135 kJ/RT) cm3 mol-1 s-1. .

PRIORITY: FR 82-6903 22 Apr 1982. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) The title ketones were obtained by the reaction of (fluoromethoxy)- and (fluoromethylthio)benzene with trihalomethylated arom. or aliph. compds., HF, and BF3. Thus, PhOCF3 was treated with 4-FC6H4CCl3 in HF under BF3 to give 4-(F3CO)C6H4COC6H4F-4. .
