Phenothiazine synthesis mechanism
WebA new phenothiazine derivative containing two dicyano-vinyl groups as the cyanide receptor on both sides was synthesized and fully characterized. The chemosensor showed an intramolecular charge transfer (ICT) absorption band at 494 nm and emission band at 633 nm in acetonitrile solution. Upon titration with different concentrations of cyanide ... WebAbstract. Alkylation of phenothiazines to prepare chlorpromazine and analogous compounds was achieved by solid-liquid phase-transfer catalysis in the presence of Aliquat 336 in the absence of any organic solvent. This simple procedure is easy and rapid.
