New substituted carbamoylimidazole derivatives of the general formula (I) ##STR1## have been prepared by reacting the appropriate substituted imidazole derivatives of the general formula (II) ##STR2## with isocyanate compounds of the general formula (III) R.sub.4 -- N .dbd. C .dbd. O (III). the new compounds of the general formula (I) are potent herbicides and fungicides. In the above formulae R.sub.1 stands for hydrogen atom or methyl group, R.sub.2 and R.sub.3 each may represent a hydrogen atom or a nitro group, or R.sub.2 and R.sub.3 may form together a --CH.dbd.--CH--CH.dbd.CH--group, which forms a six-membered ring together with the adjacent carbon atoms of the imidazole ring, and R.sub.4 stands for a cyclohexyl, phenyl, chlorophenyl or dichlorophenyl group.
通式(I)的新替代羰酰基咪唑衍生物已通过将通式(II)的适当取代咪唑衍生物与通式(III)的异氰酸酯化合物发生反应制备而成。通式(I)的新化合物是有效的除草剂和杀菌剂。在上述式中,R.sub.1代表氢原子或甲基基团,R.sub.2和R.sub.3各自可以代表氢原子或硝基基团,或者R.sub.2和R.sub.3可以共同形成一个--CH.dbd.--CH--CH.dbd.CH--基团,该基团与咪唑环的相邻碳原子一起形成一个六元环,并且R.sub.4代表环己基、苯基、氯苯基或二氯苯基。
