Tandem Kumada–Tamao Catalyst-Transfer Condensation Polymerization and Suzuki–Miyaura Coupling for End-Functionalization and Block Copolymerization of Poly( p -phenylene)

Successive Kumada-Tamao catalyst-transfer condensation polymerization (CTCP) of [4-bromo-2,5-bis(hexyloxy)phenyl]magnesium chloride ( 1 ) and Suzuki-Miyaura end-functionalization with arylboronic acid (ester) is investigated for the synthesis of poly( p -phenylene) (PPP) with a base-sensitive functional group...
