摘要

Compounds with fungicidal and insecticidal properties having formula I <CHEM> wherein W is <CHEM> n is 0 or 1; Y is O, S, NR1, or R6; the ring bond containing R4 and R5 is a single or double bond; X is independently selected from hydrogen, halo, (C1-C4)alkyl, (C1-C4)alkoxy and -HC=CH-CH=CH- thereby forming a napthyl ring; R is independently selected from (C1-C12)alkyl and halo(C1-C12)alkyl; R1 is independently selected from (C1-C12)alkyl, (C2-C8)alkenyl and aryl; R2 is independently selected from hydrogen, (C1-C12)alkyl, (C1-C12)alkoxy, halo(C1-C12)alkyl, halo(C1-C12)alkoxy, hydroxy(C1-C12)alkyl, (C1-C12)alkoxy(C1-C12)alkyl, (C1-C12)alkoxycarbonyl(C1-C12)alkyl, (C2-C8)alkenyl, halo(C2-C8)alkenyl, (C3-C10)alkynyl, halo(C3-C10)alkynyl, (C3-C7)cycloalkyl, (C3-C7)cycloalkyl(C1-C4)alkyl, epoxy(C1-C12)alkyl, PO(OR1)2(C1-C12)alkyl, R1S(O)2(C1-C12)alkyl, (R1)3Si(C1-C12)alkyl, aryl, aryloxy(C1-C12)alkyl, arylcarbonyl(C1-C12)alkyl, aralkyl, arylalkenyl, heterocyclic, heterocyclic (C1-C12)alkyl, N-morpholino(C1-C12)alkyl, N-piperidinyl(C1-C12)alkyl; R4, and R5 are independently selected from hydrogen, halo, (C1-C8)alkyl, (C1-C8)alkoxy, cyano, halo(C1-C12)alkyl, (C2-C8)alkenyl, (C3-C10 )alkynyl, aryl and aralkyl; and R6 is (C1-C12) alkylenyl and (C2-C12)alkenylenyl.
