Heather Maynard coauthored template-directed ring-closing metathesis and polymerization work with Michael J. Marsella and Robert H. Grubbs. A metal template coordinates a polyether chain and influences its cyclization.
The product distribution therefore depends on more than the catalyst's intrinsic reactivity: organization of the starting chain changes the probability of forming a ring of a particular size.[ref]

Robert H. Grubbs coauthored template-directed ring-closing metathesis research. Coordination to a template can bring reactive ends of a polyether-containing chain into an arrangement favourable for ring formation.
This connects catalysis with molecular preorganization: a template changes the accessible geometry, while a metathesis catalyst carries out bond reorganization.[ref]
