    Abstract: The present invention relates to milbemycin derivatives of the formula I (I) wherein X is hydrogen or beta -halogen, R is methyl, ethyl, isopropyl or sec-butyl and Az is a 5 membered heterocyclic aromatic ring which contains 2-4 nitrogen atoms and is attached in the 1-position and which is unsubstituted or substituted by one or two C1-C6alkyl groups. These compounds, and the acid addition salts and metal complexes thereof, are effective pesticides for controlling endo-and ectoparasites, especially for controlling neamatodes which are parasites of animals. The may be obtained by appropriate esterification in 5-position of milbemycin derivatives. The selective beta -halogenation of 14,15-epoxymilbemycin derivatives can be effected via the intermediate DELTA 13,14-15-hydroxymilbemycins with appropriate halogenating agents.

    Abstract: The compounds having the formula I: wherein Ar is an unsubstituted or substituted aromatic radical from the series comprising phenyl, biphenyl, phenoxyphenyl and naphthyl; R2 is hydrogen, fluorine or C1-C6 alkyl; and R3 is hydrogen, fluorine, C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkoxy, C1-C6-alkylthio, phenyl, phenoxy, phenylthio or C3-C7-cycloalkyl; and each aromatic substituent or aromatic moiety of a substituent is unsubstituted or mono- or poly-substituted, by halogen, C1-C4-alkyl, C1-C4-alkoxy, c1-C4-haloalkyl, nitro and/or cyano; with the proviso that R2 and R3 cannot each simultaneously be fluorine, are new. The compounds of formula 1 are particularly useful as intermediates for 1-azolyl-2-aryl-3-fluoroalkan-2-ols which have microbicidal activity, and also themselves show some fungicidal properties.

    Abstract: New compounds have the formula: wherein R1 is C1-C6 alkyl, R2 and R3, each independently of the other are hydrogen, C1-C6 alkyl, C1-C6 alkoxy, C1-C6 haloalkyl, halogen, cyano, nitro or amino or, both together in the orthoposition to each other as a -(CH=CH)2- group, complete a naphthalene ring, and R4 is a hydrazinium or ammonium ion. The new compounds are useful as active components in gametocidal compositions.
