摘要: UNSATURATED ALCOHOL-ESTERS OF THE FORMULA
H2C=C(-R2)-CH(-OH)-R1-O-AC
WHEREIN R1 REPRESENTS A DIVALENT HYDROCARBON GROUP, R2 REPRESENTS A HYDROGEN ATOM OR A LOWER ALKYL GROUP AND AC REPRESENTS AN ACYL RADICAL OF A CARBOXYLIC ACYL GROUP, ARE PREPARED, WITHOUT SUBSTANTIAL CLEAVAGE OF THE ESTER GROUP, BY ISOMERISING AN EPOXIDE FO THE GENERAL FORMULA.
2-R2,2-(CH3-),3-(AC-O-R1-)OXIRANE
USING A TRILLOWERALKYL ALUMINIUM COMPOUND AS CATALYST TO EFFECT THE ISOMERISATION. EPOXY-CITONELLYL ACETATE OBTAINABLE BY SAID ISOMERISATION REACTION IS CONVERTED INTO THE TETRAHYDROPYRAN KNOWN AS "ROSE-OXIDE" WHICH LATTER IS A VALUABLE ORDORIFEROUS MATERIAL.-
