Compounds of the formula: ##STR1## wherein R.sup.1 is H or alkyl; R.sup.2 and R.sup.3 are independently H, alkyl, aryl or substituted aryl; R.sup.4 is H or alkoxycarbonyl; R.sup.5 is H, acyl or a cation; and Z is thienyl or substituted thienyl. The compounds exhibit grass herbicide activity and are prepared via the reaction of the appropriately substituted cyclohexane-1,3-dione with the appropriate thienylmethoxyamine derivative and optionally acylating this product at the 3-hydroxy position or converting it to the cation salt.
公式为:##STR1## 其中R.sup.1为H或烷基;R.sup.2和R.sup.3独立地为H、烷基、芳基或取代芳基;R.sup.4为H或烷氧羰基;R.sup.5为H、酰基或阳离子;Z为
