Abstract
Hydroxy sulpholenes of the general formulae <FORM:1001340/C2/1> wherein R1R2 are the same or different and preferably methyl, but may be hydrogen, alkyl, aryl, alkaryl or aralkyl groups or wherein R1 and R2 together form a saturated aliphatic ring system, are made by reacting an alpha or beta sulpholene with an aldehyde or a ketone in the presence of a base, at ambient pressure, the base preferably being present in catalytic amounts and is preferably an alkali or alkaline earth metal hydroxide, carbonate or alkoxide, pyridine, triethylamine, quaternary ammonium hydroxide or an anion exchanger. The sulpholene olines may be produced by heating the product with a dehydrating agent such as potassium bisulphate. The examples describe the synthesis of compounds wherein R1 and R2 are respectively methyl methyl, methyl isobutyl and the dehydration using potassium bisulphate of the isomeric products containing R1R2 both methyl groups.
