Synthesis and Properties of Hydrazine-Embedded Biphenothiazines and Application of Hydrazine-Embedded Heterocyclic Compounds to Fluorescence Cell Imaging Hydrazine-embedded unsubstituted butterfly-shaped biphenothiazine and its sulfoxides were synthesized by dimerization of 1,9-dibromophenothiazine, which wa......
Progress in the chemistry of compounds having π-conjugated selenaheterocyclic systems is presented. The review concentrates on the most representative selenaheterocycles: selenophene, selenazoles, selenadiazoles, as well as on seleninium salts. Their aromaticity is discussed and the chemical properties...
