<p>The invention provides fungicidal compounds of formula (I) and salts thereof wherein: R<SUP>1 </SUP>is alkyl, alkenyl, alkynyl, carbocyclyl or heterocyclyl, each of which may be substituted, or hydrogen; R<SUP>2 </SUP>and R<SUP>3</SUP>, which may be the same or different, are any group defined for R<SUP>1</SUP>; cyano; acyl; -OR<SUP>a </SUP>or -SR<SUP>a</SUP>, where R<SUP>a </SUP>is alkyl, alkenyl, alkynyl, carbocyclyl or heterocyclyl, each of which may be substituted; or R<SUP>2 </SUP>and R<SUP>3</SUP>, or R<SUP>2 </SUP>and R<SUP>1</SUP>, together with their interconnecting atoms may form a ring, which may be substituted; R<SUP>4 </SUP>is alkyl, alkenyl, alkynyl, carbocyclyl or heterocyclyl, each of which may be substituted; hydroxy; mercapto; azido; nitro; halogen; cyano; acyl; optionally substituted amino; cyanato; thiocyanato; -SF<SUB>5</SUB>; -OR<SUP>a</SUP>; -SR<SUP>a </SUP>or -Si(R<SUP>a</SUP>)<SUB>3</SUB>; m is 0 to 3; when present R<SUP>5</SUP>, which may be the same or different to any other R<SUP>5</SUP>, is any group defined for R<SUP>4</SUP>; R<SUP>6 </SUP>is optionally substituted carbo- or heterocylclyl; and A is a defined linking group, or -A-R<SUP>6 </SUP>and R<SUP>5 </SUP>together with benzene ring M form an optionally substituted fused ring system.</p> |
