Abstract: Preparation of O-substituted hydroxylammonium salts of the formula IH.sub.2 NOR x HX Iwhere R is a C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkenyl radical, each of which may be halogen-substituted, and X is chlorine or bromine, by reacting in an integrated process, without isolation of intermediatesa) acetone with hydroxylammonium sulfate and sodium hydroxide solution to give acetone oxime;b) treating the solution of acetone oxime thus obtained with sodium hydroxide solution and completely removing water,c) reacting the suspension of the acetone oxime Na salt thus obtained with alkylating agents at from 0.5 to 15 bar and at up to 140.degree. C. to give acetone oxime ethers; andd) cleaving the acetone oxime ethers with acids HX to give the products I,a homogeneous, nonpolar aprotic solvent being used in all process steps a) to d).

Abstract: O-substituted hydroxylamines (I)H.sub.2 N--O--CH.sub.2 --R(I)where R is H or an organic radical, and their salts are prepared by reacting a cyclic imidoether II of a 1,4- or 1,5-dicarboxylic acid, the said imidoether containing an ether group --O--CH.sub.2 --R, with a basic compound by a method in which a primary aliphatic aminoalcohol III is used as the basic compound and the compound I is, if required, converted to its salts.

Abstract: Triazole compounds of the formulae Ia and Ib ##STR1## where R.sup.1 is hydrogen or cyclopropyl, or is C.sub.1 -C.sub.4 -alkyl, C.sub.2 -C.sub.4 -alkenyl or C.sub.2 -C.sub.4 -alkynyl, each of which is unsubstituted or substituted by methyl, ethyl, ethenyl, ethynyl, hydroxyl, fluorine, chlorine, bromine or C.sub.1 -C.sub.4 -alkoxy, or is C.sub.1 -C.sub.4 -alkoxy, C.sub.2 -C.sub.4 -alkenyloxy or C.sub.2 -C.sub.4 -alkynyloxy,R.sup.2 and R.sup.3 independently of one another are each hydrogen, straight-chain or branched C.sub.1 -C.sub.3 -alkyl, and R.sup.2 and R.sup.3 together may furthermore form a carbocyclic ring which has up to six members in each ring system and may possess bridge members, with the proviso that, in formula Ia, two or more of the radicals R.sup.1 -R.sup.3 are not hydrogen, and is hydrogen, an acyl radical CO-R.sup.5 or a sulfonyl radical SO.sub.2 R.sup.5, R.sup.5 being straight-chain or branched C.sub.1 -C.sub.

Abstract: Substituted oxime-ethers of the formulae ##STR1## where R.sup.1 and R.sup.2 independently of one another are C.sub.1 -C.sub.6 -alkyl, n is 2 or 3 and R.sup.3 is hydrogen or C.sub.1 -C.sub.6 -alkyl.

Abstract: N-(Azolylcarbamyl)-hydroxylamines of the formula ##STR1## where R is unsubstituted or substituted alkyl, alkenyl, alkoxyalkyl or cycloalkyl, or unsubstituted or substituted phenyl, phenylalkyl, phenylalkenyl or phenoxyalkyl, R.sup.1 is alkyl, alkenyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl, cycloalkylalkyl or unsubstituted or substituted benzyl, Y is CH or N and R.sup.2 and R.sup.3 are each hydrogen or alkyl, and fungicides which contain these compounds.
