Arbeiten über Phosphorsäure und Thiophosphorsäureester mit einem heterocyclischen Substituenten 9. Mitteilung 1. Aza‐Analogie I: Aza‐Analoge von Phthalimid‐, Benztriazol‐ und 1,2,3‐Benztriazin‐4(3<i>H</i>)‐on‐Derivaten

Abstract

Abstract Aza‐analogues of the known pesticidal dithiophosphates 2, 4 and 5 have been prepared by replacing the phthalimide, benzotriazole and 1,2,3‐benzotriazin‐4(3H)‐one moieties resp. in 2 by those of quinolinic acid imide (6), cinchomeronic acid imide (7) and pyrazine‐2,3‐dicarboxylic acid imide (12), in 4 by 1H‐v‐triazolo[4,5‐b]pyridine (15) and in 5 by pyrido[2,3‐e]1,2,3‐triazin‐4(3H)‐one (21). Compared to the known compounds the new esters are less or at best equally pesticidal with an equal or even higher mammalian toxicity.
