  • The selectivity of a catalytic reaction is manipulated by straining a polymer support to which the catalyst is covalently bound. Enantioselective rhodium-catalysed hydrogenation of a series of 2-acetamidoacrylates is shown to increase with macroscopic strain, with enantiomeric ratios reaching twice their initial values.

  • The mechanisms by which changes in local geometries of receptor sites lower activation reaction barriers in electronically uncoupled, remote reaction moieties remain relatively unexplored. Here, the authors demonstrate allosteric acceleration in the thermal isomerization of an alkene triggered by the binding of a metal ion to a remote receptor site.
