Research in the chemistry of heterocyclic quinoneimines. 4. Effect of mode of activation of the reagents on the reaction of 3-phenothiazinone with alkanethiols

2-Alkylthio- and 2,4-dialkylthio-3-phenothiazinones were obtained in the case of activation of 3-phenothiazinone in reactions with alkanethiols. Activation of the reagent by means of a charge accelerates the reaction significantly and is accompanied by the additional formation of 1,2-dialkylthio-3-phenothiazinones.See 1] for Communication 3.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 334–337, March, 1984.
