Ring opening metathesis polymerization of an eta super(4)-benzene complex: a direct synthesis of a polyacetylene with a regular pattern of pi bound metal fragments

The complex ( eta super(5)-C sub(5)H sub(5))Ir( eta super(4)-C sub(6)H sub(6)) reacts with Grubbs' catalyst to give a novel polyacetylene consisting of cyclopentadienyliridium bound s-cisbutadiene moieties separated by C&z.dbd; C linkages. A crystal structure of the pentamethylcyclopentadie...

Zusammenfassung:The complex ( eta super(5)-C sub(5)H sub(5))Ir( eta super(4)-C sub(6)H sub(6)) reacts with Grubbs' catalyst to give a novel polyacetylene consisting of cyclopentadienyliridium bound s-cisbutadiene moieties separated by C&z.dbd; C linkages. A crystal structure of the pentamethylcyclopentadienyl analog establishes a strong structural analogy with norbornadiene, a classical ROMP monomer.
