Upon UV irradiation in methanol, triarylacetonitrile underwent a novel α,α-elimination of two aryl groups to give biaryl and α-methoxyarylacetonitrile.However, when a methoxy group was introduced into the phenyl group, another photochemical process which gave the corresponding triarylmethane and methoxytriarylmethane as major products took place simultaneously.
Single-electron-transfer-initiated Thermal Reactions of Arylmethyl Halides. Part 11. The Reaction of Trityl Halides with Sodium Methoxide in 2,2-Dimethoxypropane

Trityl chloride (1a) and bromide (1b) furnish with sodium methoxide in 2,2-dimethoxypropane, in addition to several minor products, mixtures of the substitution products methyl trityl ether (1c) and p-methoxytriphenylmethane (2a), and of the reduction products triphenylmethane (1f) and p-diphenylmethyltritylbenzene (3a) which are the products of competing SN and single-electron transfer-initiated processes.Compound (1c) is suggested to be formed via two successive SN' processes rather than by either the SN1 or Sn2 mechanisms which are both disfavoured under the experimental conditions applied.
