Popis: | A palladium-catalyzed alternating copolymerization of [2.2.1]oxabicyclic alkenes 1 with carbon monoxide afforded isomer mixtures of polyketones 2ktn and polyketals 2ktl. Subsequent acid-induced dehydration of polymer 2 furnished novel aromatic polymers consisting of polyketones 3ktn and polyketals 3ktl units. This formal aryne/carbon monoxide copolymerization thus generated the first example of poly(aryne-alt-carbon monoxide)s, in which o-arylene and carbonyl units are incorporated in an alternating fashion. |
