Behavior of benzoins and hydroxy ketones in acid medium: II. Reactions of 1,2-bis(2,5-dimethyl-3-thienyl)-2-hydroxy-ethan-1-one with N,S-binucleophiles in trifluoroacetic acid
摘要:
1,2-Bis(2,5-dimethyl-3 -thienyl)-2-hydroxyethan-1-one reacts with thioamides, thiosemicarbazides, and methyl hydrazinecarbodithioate in trifluoroacetic acid to give the corresponding thiazole, thiadiazine, and pyrazole derivatives, respectively.

some photochromic compounds (58 diarylethenes and 9 fulgimides), the results of our spectral and kinetic studies are presented. Aiming at targeted synthesis of new photochromic compounds, the structure – photochromic behavior relationship (SPBR) for the synthesized compounds has been analyzed. The perspectives for application of these compounds in development of recording media for use in optical memory
