Abstract
As chain-growth polymerization generally forms aliphatic main chains containing units such as alkylene and alkenylene, the method has rarely been applied to the construction of arylene units. Thus, the formation/introduction of arylene groups via chain-growth polymerization remains a challenging subject in polymer chemistry. In this study, we report a formal aryne/ethylene copolymerization using 2.2.1 oxabicyclic alkenes as aryne equivalents. A palladium-catalyzed copolymerization of 2.2. oxabicyclic alkenes with ethylene followed by acid-promoted dehydration produced novel aryne/ethylene copolymers. The use of a bulky phosphine-sulfonate ligand was essential to obtain the desired copolymers with high molecular weight.
