It has long been known that alkenes can be isomerized by sulfur dioxide. The process is generally explained by invoking an ene reaction between an SO 2 molecule and the alkene to give a b,g-unsaturated sulfinic acid intermediate (e.g. 1 + SO 2 !2; Scheme 1), which then undergoes a [1,3] sigmatropic
