Phenylphenothiazine

WebPhenothiazin wird technisch durch katalysierte Umsetzung von Diphenylamin mit 2 Äquivalenten Schwefel als Oxidationsmittel in der Schmelze hergestellt. Dabei entsteht Phenothiazin und als Reduktionsprodukt Schwefelwasserstoff, welches gasförmig abgeführt wird. Das verbleibende Phenothiazin wird durch Vakuumdestillation gereinigt. WebThree materials containing a photoactive unit, 10-phenyl phenothiazine (PTH), have been studied for the visible light-mediated oxidative coupling of amines. In particular, the materials considered are assembled through the condensation of extended polyimine, polyhydrazone, or polytriazine frameworks.
