Abstract
A herbicidal compound of formula (I) ##STR1## or a salt, tautomer or cyclic derivative thereof; where R.sup.1 and R.sup.2 are hydrogen and A is an optionally substituted saturated or unsaturated chain or ring of three carbon atoms. Methods for preparing these compounds, intermediates used in the preparation and herbicidal compositions containing them are also described and claimed.
Claims5
An herbicidal compound of the formula:
- or a salt, tautomer or cyclic derivative thereof, wherein:
- R.sup.1 and R.sup.2 are hydrogen;
- R.sup.8 is fluorine, chlorine, bromine, iodine, 1,2,4-triazol-1-yl, cyano, nitrosyloxy, aminoxy, amino, azido, SCSOCH.sub.2 CH.sub.3, SCOCH.sub.3, mercapto, methylthio, methanesulphonyl or methanesulphinyl;
- R.sup.9 is hydrogen or fluorine;
- or R.sup.9 together with R.sup.8 forms an oximino group;
- R.sup.10 is hydrogen, hydroxy or amino;
- or R.sup.9 and R.sup.10 together form --O--;
- R.sup.11 is hydrogen;
- and
- R.sup.12 and R.sup.13 are each independently hydrogen, hydroxy or fluorine, with the proviso that when one of R.sup.12 and R.sup.13 is hydroxy, the other is hydrogen.
