    摘要: Compounds of forumla (I) where one of Z and Y is CO and the other is C-W-R2 and the dotted line indicates a double bond is present where necessary to meet valency requirements, W is O, S(O)¿n?, N(R?3), N(R3)N(R4), N(R3¿)O or ON(R3); R1 is hydrogen, or an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, phenyl or heterocyclyl group; R?2, R3 and R4¿, which may be the same or different, are as defined above for R1, or are acyl, or R?2 and R3 or R2 and R4 or R3 and R4¿ together with the nitrogen or oxygen to which they are attached form an optionally substituted ring which may contain other hetero atoms; each X, which may be the same as or different from any other X, is halogen, CN, NO¿2?, SF5, B(OH)2, trialkylsilyl or a group E, OE or S(O)nE where E is a group as defined hereinbefore for R?2¿ or is optionally substituted amino; or two adjacent groups X together with the atoms to which they are attached form an optionally substituted carbocyclic or heterocyclic ring; n is 0, 1 or 2; and p is 0 to 4 have fungicidal activity. Many of the compounds are novel.
