isomeric cyclopropyl cations. Ringopening of a radical intermediate in an oxidative transformation is expected to yield a single rearranged alcohol, whereas a cation isomerizes prior to ringopening, leading to two isomeric homoallylic alcohols. Oxidation of these probes by P450BM3 and P450BioI gives results consistent with a radical but not a cationic intermediate in fattyacid hydroxylation by these enzymes
