Reactivity of compounds with a diarylmethylol group: Reactivity of compounds with a diarylmethylol group. XXXIII. Ionization of 1,1-diaryl-2-(p-chlorophenoxy)ethanols and 1,1-diaryl-2-(benzyloxy)ethanols in sulfuric acid. Shklyaev, V. S.; Potemkin, K. D. (Perm. Gos. Univ., Perm, USSR). Deposited Doc.In this article, certain chemicals are used. Some of their cas registry numbers are 14426-42-7 and 89844-26-8 , VINITI 5765-82, 8 pp. Avail. VINITI (Russian) 1982. DOCUMENT TYPE: Report CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 22 Grignard reaction of ROCH2CO2R1 (R = p-ClC6H4, R1 = Et; R = R1 = PhCH2) with p-R2C6H4X (R2 = H, Me, MeO, Cl, Br; X = halo) gave 10 corresponding ROCH2C(C6H4R2-p)2OH (I) in 58-71% yield. Dehydrating I (R = p-ClC6H4, R2 = Cl) with 85% H2SO4 in AcOH gave 74% p-ClC6H4OCH:C(C6H4Cl-p)2. The pKa values of I (R = p-ClC6H4) (II) correlated with the Brown-Okamoto s+ consts. of R2 (r = -3.36). Radical cations were obsd. on treating I (R = PhCH2) but not II with H2SO4, complicating the detn. of pKa values for the former. .
