Alkyl isocyanates where R is methyl and ethyl have been prepared by this reaction in yields of 43% and 95%, respectively. Diphenylmethyl bromide also serves as an alkylating agent to give diphenylmethyl isocyanate (80%). ... [Pg.772]

Twenty grams (0.12 mole) of diphenylmethane is heated to 150-160° while 7 ml. (22 g., 0.14 mole) of bromine is added slowly, (/food.) The product is distilled under vacuum, and diphenylmethyl bromide boiling at 183°/23 mm. is obtained in 86% yield. [Pg.144]

To a solution of 42 g. (0.23 mole) of benzhydrol [Org. Syntheses Coll. Vol. 1, 90 (1941)] in 125 g. of carbon tetrachloride is added slowly 27 g. (0.10 mole) of phosphorus tribromide. The mixture is allowed to stand for a day and then is heated to 60-70° for 6 hours. The reaction mixture is filtered, washed with ice water then with dilute sodium acetate solution, dried over calcium chloride, and distilled. The diphenylmethyl bromide is obtained in 65% yield (36 g.) boiling at 172-176°/14 mm. and melting at 43-45°. [Pg.144]

Cyclic allenes with nine and ten carbon atoms,151 polyhaloallenes,152 and arylallenes153,154 have been prepared by dehydrohalogenation reactions. Tetraphenylallene has been obtained in quantitative yield from diphenyl-ethylene and diphenylmethyl bromide through various intermediates, thus 153... [Pg.834]

Diphenylmethyl bromide allowed to react 5 hrs. at room temp, with triethylamine-borane complex in nitromethane -> diphenylmethane. Y ca. 100%. - The yields depend on the stability of the carbonium ions derived from the halides. Prim, halides can not be reduced by this method. F. e., also in liq. SO2, s. S. Matsumura and N. Tokura, Tetrah. Let. 1968, 4703 with diborane in nitromethane s. Tetrah. Let. 1969, 363. [Pg.306]
