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.
of these two diarylethenes exhibits typical reversible absorption and fluorescence changes upon UV or visiblelight irradiation, and their diverse response to light irradiation is investigated by X-ray single crystal analysis and also DFT calculation. The investigation presented here provides valuable insight into the designing and development of diarylethene-based fluorescent switches in the solid
