The authors successfully perform cross-metathesis on an allyl substrate placed on a flexible loop of the serine protease subtilisin (Fig. 1). It will be valuable to determine whether an alkene ...

in a reaction known as “olefin metathesis.” A molecule of propene is released as the result of this process. The shorter polymer chain which results (right) has a carbon-carbon double bond at ...

This class of reactions involves ... work on the catalytic synthesis of alkene polymers with controlled molecular structures. Natta initiated the use of metathesis for polymerization of cyclic ...
