| titleOfInvention | Process for the preparation of 2-(4-chlorophenylethyl)-2-tert.-butyl-oxirane |
| abstract | A process for making the known fungicide intermediate 2-(4-chlorophenyl ethyl)-2-tert.-butyloxirane of the formula ##STR1## comprising (a) mixing a solution of trimethylsulphonium bromide of the formula n n (CH.sub.3).sub.3 S.sup.⊕ Br.sup.⊖ (II) n n in a methanol/toluene mixture with preheated toluene and simultaneously distilling off a methanol/toluene mixture at a temperature between 65° and 110° C. until a suspension having a solids content between 10 and 70% by weight is formed, and n (b) reacting the suspension of trimethylsulphonium bromide in toluene thus obtained with 1-(4-chlorophenyl)-4,4-dimethylpentan-3-one of the formula ##STR2## in the presence of solid potassium hydroxide, diethylene glycol and water at a temperature between 20° and 120° C., the amounts of the reaction components being such that per mole of 1-(4-chlorophenyl)-4,4-dimethylpentan-3-one of the formula (III) there are present n between 1 and 2 moles of trimethylsulphonium bromide of the formula (II), n between 2 and 3 moles of solid potassium hydroxide and also n between 0.1 and 10% by weight of diethylene glycol and between 0.5 and 12% by weight of water, relative to 1-(4-chlorophenyl)-4,4-dimethylpentan-3-one of the formula (III). |
