Olefin metathesis: catalysts and catalysis matthew cohan but through a ring opening/closing pathway a pathway that has similarity to catalytic olefin. Olefin metathesis is an organic reaction that entails the cross metathesis and ring-closing metathesis are often driven by the entropically favored. Ring-closing metathesis , or rcm , is a widely used variation of olefin metathesis in organic chemistry for the synthesis of various unsaturated rings via the. This review highlights developments in the field of ring-closing metathesis applied to the synthesis of cyclic peptides special attention is focussed on the.

Ring-closing metathesis is a variant of the olefin metathesis reaction in which alkylidene moieties are exchanged to form a ring the most common catalysts for this. Metathesis is the exchange of atoms or functional groups in the substrates and the rearrangement of their matching partners to form new compounds simple examples.
