A process for the preparation of an oxirane of the formula ##STR1## in which Y is chlorine or phenyl,

Preparation of oxiranes

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 formula

Process for the preparation of hydroxybenzaldoxime o-ethers

A process for the preparation of oxiranes is disclosed in which a ketone of the formula ##STR1## wherein Y represents chlorine or phenyl, X represents oxygen or CH.sub.2 and Z represents hydrogen or halogen is reacted with trimethylsulphonium methyl sulphate formed by treating dimethyl sulphide with dimethyl sulphate. The process is carried out in the presence of potassium hydroxide or sodium hydroxide powder in an inert organic diluent at 0.degree. to 60.degree. C. The products are useful as intermediates for the formation of plant growth regulants and fungicides.

Process for the preparation of oxiranes

A substituted azolylvinyl ketone or carbinol of the formula ##STR1## in which R.sup.1 represents optionally substituted cycloalkyl with 3 to 5 carbon atoms, substituted cyclohexyl or the grouping ##STR2## wherein R.sup.3 represents optionally substituted phenyl, alkenyl, alkinyl, cyano or the grouping --Z--R.sup.4, wherein

Substituted azolylvinyl ketones and carbinols as fungicides and plant

A process for the preparation of an oxirane of the formula ##STR1## in which X is 4-chlorobenzyl, 4-phenylphenoxy or 1H-(1,2,4)-triazolyl, comprising reacting dimethyl sulphate with an excess of dimethyl sulphide thereby to form trimethylsulphonium methyl-sulphate of the formula

A plant growth-inhibiting composition comprising ##STR1## wherein the various radicals are as defined.

Synergistic compositions for inhibiting plant growth

A process for the preparation of oxiranes is disclosed in which trimethylsulphonium methyl sulphate, formed by treating dimethyl sulphide with dimethyl sulphate in the presence of tert.-butanol, is reacted, without previous isolation, with a ketone in the presence of a base and in the presence of tert.-butanol. The resultant oxiranes are useful in the preparation of plant growth regulants and fungicides.

A synergistic fungicidal composition comprising a fungicidally effective amount of at least one amino compound of the formula ##STR1## in which R represents optionally substituted cycloalkyl or optionally substituted aryl,
