- Process for the preparation of oxiranes
-
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 CH2 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° to 60° C. The products are useful as intermediates for the formation of plant growth regulants and fungicides.

- Oxirane compounds
-
Oxirane compounds of the formula STR1 in which R represents tert-butyl, iso-propyl radical, cyclopropyl, substituted cyclopropyl, cyclopentyl or substituted cyclopentyl, cyclohexyl or substituted cyclohexyl, in each case the substituent being selected from methyl, or phenyl which is optionally mono or di-substituted by identical or different substituents selected from fluorine, chlorine, methyl and trifluoromethyl, Y represents a grouping --OCH2 --, each Z is individually selected from the group consisting of a fluorine, chlorine or bromine atom, methyl, tert-butyl, cyclohexyl, methoxy, methylthio, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, phenyl, phenoxy, benzyl and benzyloxy, said phenyl, phenoxy, benzyl and benzyloxy being optionally mono or di-substituted by identical or different substituents selected from fluorine, chlorine and methyl, m is 0, 1, 2 or 3; these compounds are particularly useful as intermediates for compounds used in agricultural compositions as plant growth regulants.
