Novel 1-alkylideneaminouracil compounds of the formula ##STR1## in which R.sup.1 is optionally substituted hydrocarbyl which may contain hetero-atoms. R.sup.2 is hydrogen or halogen; and R.sup.3 is hydrogen or alkyl; or R.sup.2 and R.sup.3 together represent a multi-membered methylene bridge which forms, with the two carbon atoms in the 5- and 6-position of the heterocyclic structure, a fused ring which is optionally substituted by alkyl. R.sup.4 is alkyl, cycloalkyl, cycloalkenyl, optionally substituted 5-membered or 6-membered heteroaryl with the hetero-atoms O, N or S; and R.sup.5 is hydrogen, alkyl or optionally substituted aryl; advantageously employ the selective herbicides in crops, e.g., in cotton or cereal crops.
公式为##STR1##的新型1-烷基亚氨基尿嘧啶化合物,其中R.sup.1为可选取代的含杂原子的碳氢基团。R.sup.2为氢或卤素; R.sup.3为氢或烷基; 或者R.sup.2和R.sup.3共同表示多元的亚甲基桥,它与杂环结构的5-和6-位的两个碳原子形成一个融合环,该融合环可选地被烷基取代。R.sup.4为烷基,环烷基,环烯基,可选取代的含有O、N或S杂原子的5-或6-元杂芳基; R.sup.5为氢,烷基或可选取代的芳基; 优选在作物中使用选择性除草剂,例如在棉花或谷物作物中。
