chain-walking hydroboration to create a one-pot, contra-thermodynamic, short- or long-range isomerization of internal olefins to terminal olefins. This dehydroboration occurs by a sequence comprising activation with a nucleophile, iodination, and base-promoted elimination. The isomerization proceeds at room temperature without the need for a fluoride base, and the substrate scope of this isomerization is expanded

A process for preparing primary substituted n-alkane compounds, comprising contacting the olefin product of an olefin metathesis reaction having an alpha-olefin as the reactant with a bis-cyclopentadienyl zirconium hydrohalide and, after contacting the product of the olefin-zirconium hydrohalide reaction with an electrophilic reagent, recovering said primary substituted n-alkane compound.
