Abstract
Inventia se refera la un procedeu de preparare a unor derivati de uree, cu actiune erbicida, cu formula generala I: (vezi formula) în care x reprezinta o grupa (vezi formula) R reprezinta alchil inferior, n reprezinta 0 sau 1, si m reprezinta 0 sau un numar întreg de la 1 la 6, prin tratarea unui mol de dimer de izocianat cu formula genereala II: (vezi formula) în care X are semnificatiile de la formula I, cu doi moli de amina cu formula generala III: (vezi formula) în care R, m si n au semnificatiile de la formula generala I, în toluen în calitate de mediu inert de reactie, la temperatura camerei.The invention relates to a process for the preparation of urea derivatives of herbicidal action of the general formula I wherein X represents a group (see formula) R represents lower alkyl, n represents 0 or 1 and m represents 0 or an integer from 1 to 6 by treating one mole of the isocyanate dimer of the general formula II: wherein X is as defined in formula I with two moles of the amine of general formula III: see formula) wherein R, m and n have the meanings of general formula I in toluene as the reaction inert medium at room temperature.
