(from preface)The 9th quantity of Advances in Heterocyclic Chemistry comprises surveys of the chemistry of the subsequent teams of heterocyclic compounds: 1,2,5-thiadiazoles (L. M. Weinstock and P. I. Pollack); 1,3,4-thiadiazoles (J. Sandstrom); pyridazines (M. Tisler and B. Stanovnik); Reissert compounds (F. D. Popp); phenothiazines (C. Bodea and that i. Silberg); and pyrrolopyridines (R. E. Willette).Suggestions are welcomed for contributions to destiny volumes; they need to be within the kind of brief synopses.Thanks are as a result of the Editorial Board, the writer, and the authors for his or her cooperation.
