Process of manufacturing arylalkyl and alkyl mercaptans. Chen, Mabel Mei Mei (Atochem North America, Inc., USA). Eur. Pat. Appl. EP 476339 A1 25 Mar 1992, 6 pp. DESIGNATED STATES: R: AT, BE, CH, DE, DK, ES, FR, GB, GR, IT, LI, LU, NL. (European Patent Organization). CODEN: EPXXDW. CLASS: ICM: C07C319-02. ICS: C07C321-02. APPLICATION: EP 91-113988 21 Aug 1991. PRIORITY: US 90-585350 19 Sep 1990. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) The title compds. were prepd. by reaction of an org. 70384-51-9 and 16721-80-5 are also in the experiment. halide with an alkali metal hydrosulfide in the presence of H2S and a phase-transfer catalyst in H2O. Thus, PhCH2Cl and NaSH reacted in the presence of H2S and polyethylene glycol to give an org. product contg. 83 wt. % PhCH2SH, which was distd. under vacuum to give high-purity (99.6% wt. %) PhCH2SH. .

(Difluoromethoxy)- or (difluoromethylthio)arenes.Some chemicals with cas registry numbers like 106-44-5 and 70384-51-9 are also used. Langlois, Bernard (Rhone-Poulenc Specialites Chimiques, Fr.). Fr. Demande FR 2529543 A1 6 Jan 1984, 11 pp. (French). (France). CODEN: FRXXBL. CLASS: IC: C07C021-24. APPLICATION: FR 82-11720 5 Jul 1982. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) The prepn. of ethers and sulfides from phenols and benzenethiols and RCHF2 (R = Cl, Br, iodo) was catalyzed by N[CHRCHR1O(CHR2R3O)nR4]3 (n is an integer of 0-10; R, R1, R2, and R3 are H, alkyl; R4 = alkyl, cycloalkyl, Ph, phenylalkyl). Thus, PhOH was treated with ClCHF2 and N[(CH2CH2O)2Me]3 to give PhOCHF2. .
