Abstract
A process for regioselective isomerization of organic compounds having a carbon-carbon double bond at a tertiary carbon atom by sulfur dioxide induced allylic rearrangement of a hydrogen atom and/or replacement of a proton in the allylic position by a deuteron. The organic compound is contacted with sulfur dioxide at temperatures between about 0.degree. and 70.degree. C. for a time sufficient to effect such isomerization to a more stable isomer; and if deuteration is to take place D.sub.2 O is provided in the solution.
