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

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).

HIGH COST OF THE DEMAND FOR ZERO RISK

The cost of a common childhood vacination, for diphtheria, pertussis and tetanus, rose from 50 cents in 1982 to $11.40 in 1986, as its manufacturer, the Lederle Laboratory division of American Cyanamid Company, amassed cash to pay legal claims for rare but predictable side effects.

Territory Sales Response

What factors account for the wide variation in performance with in a salesforce, and what is the relative importance of these factors? The authors attempt to answer that question by first developing a framework that identifies the major constructs to be included in a model of territory response, and then testing the model in three different corporate settings. The empirical results provide a basis for useful generalizations about the importance of territory characteristics, span of control, and other factors in explaining the variability in salesperson performance.
