Beschreibung
Zusammenfassung:	A compound of the formula wherein R represents a lower alkyl group, R represents a hydrogen atom or a lower alkyl group, and Z represents a group of the formula -OR or -SR in which R represents a lower alkenyl or alkynyl group which may be substituted by halogen, cyano or lower alkoxycarbonyl, and R represents a lower alkyl group. The above compound is produced by (a) reacting an ester-forming derivative of a compound of the formula wherein R and R are as defined above, and Q represents an oxygen or sulfur atom, with a compound of formula Z-H (III) wherein Z is as defined above, or (b) reacting the compound of formula (II) with a compound of the formula R X or R X (IV) wherein R and R are as defined above, and X represents a halogen atom, or (c) reacting a compound of the formula wherein R and Z are as defined above, with a compound of the formula R -X (VI) wherein R is as defined above, and X represents an acid residue, or diazomethane. This compound is useful as a herbicide.
