Acyclic diene metathesis
Following on from part ii of this review in which platinum group metals catalysts taking part in ring-closed metathesis reactions were considered, part iii looks at this group of catalysts as they are used for acyclic diene metathesis reactions and for ring-opening metathesis polymerisations.
