Montmorillonite K10 clay catalysed Baeyer condensation of heterocyclic aldehydes with <i>N,N</i>-dimethylaniline: Synthesis and photo irradiation studies of heteroaryldiarylmethanes^†

Abstract

1258-1263The montmorillonitemK10 clay catalysed Baeyer condensation of a number of aromatic heterocyclic aldehydes (1-7) with N,N-dimethylaniline affords novel triarylmethanes (8-14) in good yield. The triarylmethane 8 was irradiated at 325 nm for 1 hr under different solvent systems and the photoproducts were identified as 15 and 16
