Abstract: Method of influencing plant growth, characterised in that the soil, the seed and/or the plants are treated with an azolyl methyl oxirane of the formula in which the substituents A and B represent C1-C4-alkyl, phenyl, naphthyl, diphenyl or phenyl which is substituted by one to three radicals from amongst the group comprising halogen, C1-C4-alkyl, C1-C4-alkoxy, C1-C4-haloalkyl, nitro or phenoxy and Z represents the CH group or nitrogen, or their metal salts or acid addition salts, and compositions for influencing plant growth which contain at least one azolyl methyl oxirane.

Abstract: Prodn. of phenylacetaldehydes of formula Ar-CH2-CHO (I) is effected by (a) contacting an epoxide or glycol deriv. of formula Ar-CHY-CH2Z (II) with a borosilicate zeolite catalyst in the gas phase at 70-200 deg.C under reduced pressure or (b) contacting a phenylglycidate ester of formula (III) with a zeolite, phosphate, supported H3PO4, supported H3BO3 and/or acidic metal oxide catalyst in the liq. or gas phase at 50-500 deg.C and 0.01-50 bar, Ar is phenyl with 0-5 substits. selected from halogen and opt. halogenated alkyl, alkenyl, alkylthio and cycloalkyl, Y and Z are OH, alkoxy, aryloxy or acyloxy or Y+Z is O, R6 is t-Bu or i-Pr.

Abstract: Process for the production of alpha , alpha -dialkoxyketones of the general formula I in which R and R independently of one another are hydrogen, C1- to C20-alkyl, C3- to C20-cycloalkyl, C4- to C30-cycloalkylalkyl, C9- to C30-alkylcycloalkyl, or optionally C1- to C8-alkyl-, C1- to C8-alkoxy-, halogen-, C1- to C4-haloalkyl-, C1- to C4-haloalkoxy-, phenyl-, phenoxy-, halophenyl-, halophenoxy- and/or cyano-substituted aryl, C7- to C20-aralkyl or heterocycle, R is additionally R and R independently of one another are C1- to C20-alkyl, C3- to C20-cycloalkyl, aryl, C7- to C20-arylalkyl, or together are a C2- to C7-alkylene chain which is optionally substituted by C1- to C4-alkyl, and R is R or together with R is a C2- to C7-alkylene chain which is optionally substituted by C1- to C4-alkyl, by reacting ketones or aldehydes of the general formula II with nitrites of the general formula III R -(NO2)n (III> in which n is 1 or 2, and n is 2 if R and R together represent a C2- to C7-alkylene chain which is optionally substituted by C1- to C4-alkyl, with the proviso that the nitrite groups are terminal, or with a mixture of alcohol of the general formula IV R -(OH)n IV in which n is 1 or 2, and n is 2 if R and R together represent a C2- to C7-alkylene chain which is optionally substituted by C1- to C4-alkyl, with the proviso that the hydroxyl group is terminal, and with dinitrogen trioxide in a molar ratio of 2:1 in the presence of an acid catalyst, at temperatures from 0 to 170 DEG C.

Abstract: Trifluoromethylphenylazolylmethyloxiranes of the general formula I in which R represents hydrogen, halogen, nitro, phenyl, phenoxy, alkyl, alkoxy, haloalkyl or haloalkoxy, and, moreover, R together with the phenyl ring can also form a naphthyl radical which is unsubstituted or substituted, n represents an integer from 1 to 5, R represents ortho- or para-trifluoromethyl, X represents CH or N, and their acid addition salts and metal salts which are tolerated by plants, and fungicides containing these compounds.

Abstract: Phenylacetaldehydes of the general formula I (I) where R1 to R5 are each independently of the others hydrogen, alkyl, alkoxy, halogen, haloalkyl, haloalkoxy or haloalkylthio, by catalytic rearrangement in the presence of a zeolite, are prepared by reacting an epoxy of the formula II or a phenylglycol of the formula III (II) (III) where Y and Z can be identical to or different from each other and are each hydroxyl, alkoxy, aryloxy or acyloxy, in the gas phase over a borosilicate zeolite catalyst at from 70 DEG to 200 DEG C. under reduced pressure.
