Abstract: Hydroxybenzaldoxime O-ethers of the formula ##STR1## in which R.sup.1 represents alkyl,are obtained by a process in which a tert.-butoxy-benzaldoxime of the formula ##STR2## is reacted with alkylating agents of the formulaR.sup.1 --Xin whichR.sup.1 has the abovementioned meaning andX represents halogen or OSO.sub.2 OR.sup.1,whereinR.sup.1 again has the abovementioned meaning,in the presence of a strong base and phase transfer catalyst and in the presence of a diluent at temperatures between 0.degree. C. and 50.degree. C., and the products are then treated with anhydrous acid at temperatures between 0.degree. C. and 50.degree. C.,Hydroxybenzaldoxime O-ethers can be used as intermediate products for the synthesis of compounds with a fungicidal, insecticidal and antimycotic activity. The tert.-butoxy-benzalodoxime starting material is a new compound.

Abstract: Combating fungi with novel 1-azolyl-substituted oxime ethers of the formula ##STR1## in which R is alkyl, alkoxyalkyl, alkenyl, alkinyl or cycloalkyl; or aralkyl, phenoxyalkyl or phenyl optionally substituted in the aromatic part,R.sup.1 is alkyl, alkenyl, alkinyl, or optionally substituted aralkyl or heteroalkyl, andX is nitrogen or the CH group,or physiologically acceptable addition products thereof with acids or metal salts.

Abstract: An N-sulphenylated oxime-carbamate of the formula ##STR1## in which R.sup.1 is optionally substituted alkyl, cycloalkyl, aryl or aralkyl,R.sup.2 is alkyl, alkenyl or alkynyl, orR.sup.1 and R.sup.2 together are an alkylene bridge having 1-6 C atoms, one of R.sup.3 and R.sup.4 is the radical ##STR2## and the other is alkyl, alkenyl, alkynyl, halogenoalkyl, halogenoalkenyl or alkoxyalkyl,R.sup.5 is alkyl,R.sup.6 is alkyl, halogenoalkyl, optionally substituted phenyl, alkoxycarbonyl or dialkylamino, NR.sup.8 --SO.sub.2 R.sup.7, or a radical identical to the radical to which the grouping --S--R.sup.6 is bonded,R.sup.7 is alkyl, dialkylamino or optionally substituted phenyl,R.sup.8 is alkyl, andX is O or S,which possesses pesticidal activity.

Abstract: Hydroxamic acid esters of the formula ##STR1## in which R.sup.1 is an optionally substituted alkyl, cycloalkyl, aryl or aralkyl radical andR.sup.2 is an alkyl, alkenyl or alkinyl radical, orR.sup.1 and R.sup.2 together are an alkylene bridge with 2 to 4 carbon atoms,one of the radicals R.sup.3 and R.sup.4 is ##STR2## while the other is an alkyl, alkenyl, alkinyl, halogenoalkenyl or alkoxyalkyl radical, andX is O or S,which possess pesticidal properties. Intermediates therefor wherein one of N--OR.sup.3 and N--OR.sup.4 is N--OH or a carbonyl group are also new.
