(3-methyl-2-cyclohexenyl) phenyl sulfone
in 400 cm3 Ameisensäure bringt man 34,2 g rohes 3-Methyl-2-cyclohexen-l-ol ein, fügt 68 g Natriumphenylsulfinat zu und rührt etwa 15 Minuten bei Raumtemperatur. Man gießt in eine Mischung von Wasser und Eis, extrahiert mit Methylenchlorid, vereinigt die Methylenchloridextrakte, wäscht die erhaltene Lösung mit Wasser, dann mit einer wäßrigen Natnumbicarbonatlösung und schließlich mit Wasser,34.2 g of crude 3-methyl-2-cyclohexen-1-ol are introduced into 400 cm 3 of formic acid, 68 g of sodium phenylsulfinate are added and the mixture is stirred at room temperature for about 15 minutes. It is poured into a mixture of water and ice, extracted with methylene chloride, the methylene chloride extracts are combined, the resulting solution is washed with water, then with an aqueous sodium bicarbonate solution and finally with water,
