Abstract
Starting from acetylacetone 1, boric acid and a diol, or a 2-aminothiazole 16 and perchloric acid several dimethyl-substituted 1,3,2-dioxaborines 5 an d thiazolo[3,2a]-pyrimidinium salts 17, resp., have been prepared and trans formed by raction with 4-N,N-dimethylamino-benzaldehyde 3a or 3-methyl-2-me thylmercapto-benzthiazolium perchlorate 13 into deeply colored polymethine dyes 11, 12, 14, 15, and 18-21, and 23-24 their spectroscopic data were rec orded.
