Synthesis and properties of certain n-propargylphenothiazines and their cation radicals

Abstract

N-Propargyl derivatives of 3-thiocyanato-, 2-chloro-, and 7-thiocyanato-2-chlorophenothiazines have been synthesized. Their capability for one-electron oxidation, forming cation radicals, has been investigated. EPR spectra of cation radicals obtained by different methods have been examined. © 1994 Plenum Publishing Corporation.
