Compounds of the formula <IMAGE> wherein R1 is a group of the formula: <IMAGE> (a) <IMAGE> (b) <IMAGE> (c) wherein A is divalent oxygen, sulfur, sulfinyl, or sulfonyl; A1 is divalent oxygen, sulfur, sulfinyl, sulfonyl or -NH-; X is hydrogen, chloro, bromo, iodo, nitro, C1-C3 alkyl, hydroxy, C1-C3 alkoxy, mercapto, C1-C3 alkylthio, carbamyl or C1-C3 alkylcarbamyl; X1 is chloro, bromo or iodo; R2 is hydrogen, C1-C18 alkyl or C2-C18 alkenyl; W is C1-C10 alkylene or C2-C10 alkenylene; m, n and p are 0 or 1, but if m=0, n must=0; provided: that the sum of the carbon atoms in the R2 and W groups must be greater than 4 but cannot exceed 21; that when X is mercapto. A and A1 cannot be sulfinyl or sulfonyl; and that when A and A1 are sulfinyl or sulfonyl, they must be in equal oxidation states.
