Fit securely to the lower end of the condenser (as a receiver) a Buchner flask, the side-tube carrying a piece of rubber tubing which falls well below the level of the bench. Steam-distil the ethereal mixture for about 30 minutes discard the distillate, which contains the ether, possibly a trace of unchanged ethyl benzoate, and also any biphenyl, CeHs CgHs, which has been formed. The residue in the flask contains the triphenyl carbinol, which solidifies when the liquid is cooled. Filter this residual product at the pump, wash the triphenyl-carbinol thoroughly with water, drain, and then dry by pressing between several layers of thick drying-paper. Yield of crude dry product, 8 g. The triphenyl-carbinol can be recrystallised from methylated spirit (yield, 6 g.), or, if quite dry, from benzene, and so obtained as colourless crystals, m.p. 162. ... 

Steam-distil the ethereal solution and discard the distillate. The residue in the flask is triphenyl-carbinol and solidifies on cooling. Filter at the pump, wash with water, drain and dry. Yield of crude product 0 6 g. Recrystallise when dry from benzene to obtain colourless crystals m.p. 162°. 

The spectra and halochromism of thiophene analogs of triphenyl and diphenyl carbinol, " the spectra of anilides of 2- and 3-thenoyl-acetic acid, " and the fluorescence of some thiophene compounds have been investigated. 

The condensation of thiophene with ketones, under the influence of 70% H2SO4, leads to di-2-thienylmethane derivatives. With acetone, 2,2-di-(2-thienyl) propane (97) is obtained. The condensation of thiophene with dimethyl phenyl carbinol, methyl diphenyl carbinol, and f-butylalcohol, in the presence of SnCU gave (98), (99), and 2,5-di-f-butylthiophene, respectively. Triphenyl carbinol does not... 

The palladium-catalyzed reaction of o-iodoanilides with terminal acetylenic carbinols provides a facile route to the synthesis of quinolines using readily available starting materials (93TL1625). When o-iodoanilide 126 was stirred with acetylenic carbinol 127 in the presence of bis-triphenyl phosphine palladium(ll) chloride in triethylamine at room temperature for 24 h, the substituted alkynol 128 was obtained in 65% yield. On cyclization of 128 with sodium ethoxide in ethanol, 2-substituted quinoline 129 was obtained in excellent yield. 

Furthermore, the electrostatic theory cannot explain why a given material may behave very differently in two different media of the same dielectric constant water as well as concentrated sulfuric acid have a dielectric constant of about 80. Perchloric acid is completely dissociated in water but is a nonelectrolyte in sulfuric acid, whereas triphenyl carbinol is completely dissociated in sulfuric acid and non-dissociated in water.
