How are ring closing metathesis and cross metathesis related?

Ring-closing metathesis is an intramolecular reaction of an acyclic diene to form a ring (Fig. 1), while cross metathesis brings two olefins together in an intermolecular reaction to give an olefin product bearing substituents from each of the starting olefins (Fig. 2). + metathesis catalyst Figure 1. Ring-closing metathesis (RCM)

Why is cross metathesis an alternative to olefination?

Cross metathesis (CM) is an attractive alternative to other olefination methods due to the large variety of commercially available olefin starting materials and to the high functional group tolerance of the ruthenium metathesis catalysts.

Which is an example of a cross metathesis reaction?

Depending on the types of olefins involved in the metathesis reaction, cross metathesis reactions generally fall into one of three types: I. Chain-extending. This brings together two olefins to make a longer chain molecule, an example being the CM of 1-octene with itself to produce 7-octadecene and ethylene gas.

Which is the most common form of metathesis?

The simplest form of metathesis is cross-metathesis, involving the intermolecular reaction of two alkene units in the presence of a metathesis catalyst. Cross-metathesis of two dissimilar monosubstituted alkenes, the most common situation in cross-metathesis, is represented by the general reaction equation in Scheme 7.
