Preparation, 1H and 13C NMR Spectra of Substituted 2-Benzoylaminocarboxamides

Abstract

A new type of herbicides based on imidazolinones has been introduced into agriculture under commercial names of Arsenal, Pursuit, Scepter, Assert etc. by American Cyanamid Company since 1983. These compounds destroy diocotyledonous weeds and are almost nontoxic for mammals and fish (LD50 rat - 500 mg/kg, LD50 trout - 300 mg/kg) and nonmutagenic according to the AMES test. The aim of the present work is to synthesize substituted 2-benzoylaminocarboxamides as starting materials for preparation of imidazolinones and potential biologically active substances (Formulae I - III).
