Carbon-carbon bond formation/cleavage on transition metals has been almost exclusively investigated due to the numerous contributions to organic synthesis. In this cluster, carbon-carbon bond formation/cleavage on transition metals were applied to develop new synthetic methodologies for polymers or oligomers.
@Processes for producing co-oligomers with high regioregularity are important objects in many researches. Herein, metallacycle-including polymer or oligomer were synthesized. Through the carboncarbon bond formation/cleavage on transition metals, the metallacycle moiety was converted to a variety of aromatic rings. Subsequently, a variety of highly regioregular co-oligomers were synthesized from the same metallacycle-including oligomer.
