“…A solution of benzhydrol (75.6 mg, 0.413 mmol) and naphthalene (28.3 mg, 0.221 mmol) was prepared in benzene (2 mL). A glass capillary (10 cm, 9 mm OD, 2.5 mm ID) was filled with 25 pL of this solution, degassed and sealed under argon, and heated for 20 min in the sandbath at 400 °C. Upon cooling to room temperature, the capillary was cooled under liquid nitrogen and opened and the contents were extracted into chloroform.…”

“…Thus when -toluenesulfonyl azide is thermally decomposed in aniline or dimethylaniline, some sulfur dioxide and nitrogen are evolved and 4,4'-diaminotriphenylmethane or 4,4'-bis(dimethylamino)triphenylmethane is formed (97). The diphenylmethylene radical, (C6H5)2C:, from diazodiphenylmethane, does not attack benzene (354) and takes hydrogen from the side chain of benzyl methyl ether (28), but with phenol it gives small amounts (2 to 3 per cent) of o-(diphenylmethyl)phenol (61,356). The ethoxycarbonylmethylene radical, C2H5OCOCH:, derived from ethyl diazoacetate, is well known to add to a benzene ring and yield a bicyclo compound containing a cyclopropane ring.…”

“…It is of significance that diphenylmethyl bromide and phenol (51) or benzyl chloride with diphenyl, benzene, toluene, o-xylene, or mesityl ene will yield, at elevated temperatures without a catalyst, normal condensation products (292). This emphasizes the fact that the alkylation by metal halides is essentially an activation reaction occurring when suitable activity of the nuclear hydrogen and the aliphatic halogen are realized.…”
