The reaction of N-substituted anilines 2 with diphenylmethyl halides 1 at room temperature in the presence of AlCl3 affords p-substituted derivatives 3 in good yields according to an electrophilic aromatic substitution. In contrast, aniline itself is only converted to the N-substituted compounds 4. A novel rearrangement from Ph3C-NHPh (4c) to p-(triphenylmethyl)aniline (5) is described. Unexpected photofragmentations of 4a, b are studied by using ESR and ENDOR spectroscopy; e.g., irradiation of 4b with quartz- or pyrex-filtered light leads to the formation of the radicals Ph2C-SiMe3 (7b) and Ph2C - NHPh (6) respectively, following selective cleavage of the C - N and C - Si bond.
