A rhodacyanine dye, 1-ethyl-2-[[3-ethyl-5-(3-methylbenzothiazolin-2-ylidene)-4-oxothiazolidin-2-ylidene]-methyl] pyridinium chloride (MKT 077, 1) was oxidized by self-sensitized singlet oxygen to produce two carbonyl compounds under photo-radiation, one of which was further rearranged via Norrish Type I like cleavage to give new types of merocyanine dyes (5 and 8). The merocyanine dyes were also synthesized by the treatment of thioamide (6) with oxalyl chloride. (C) 1998 Elsevier Science Ltd. All rights reserved.

The synthesis of a series of 1-[(4-fluorophenyl)methyl]-N-(4-piperidinyl)-1H-benzimidazol-2-ami nes and the preliminary evaluation of their in vivo antihistamineactivity are described. The title compounds were obtained starting from either 1, 4, 10, or 55 by different synthetic methods. Substitution on the phenyl nucleus of the benzimidazole ring (84-87) was achieved by two different approaches. The
