Diarylacetylenes and diarylenamines are synthesized from a Schiff's base and an N-arylmethylheterocycle; these compounds are useful as intermediates for a variety of polymers; in particular an efficient process is provided for producing diaryl acetylenes useful in the efficient production of acetylene group-containing polymers which can be cross-linked to produce high strength polymers free of structural defects such as conventionally arise as a result of liberation of volatiles during the cross-linking.

A new protocol has been developed to synthesize N1-vinyl benzotriazoles from 1-arylmethylbenzotriazoles by treatment with arylaldehydes and LiN(SiMe3)2. The reaction proceeded smoothly in the absence of transition metals, showing excellent Z selectivity and broad substrate scope with good functional group tolerance.

Ces composés peuvent être utilisés comme intermédiaires pour une variété de polymères. On décrit en particulier un procédé efficace permettant de produire des acétylènes de diaryle pouvant être utilisés pour la production efficace de polymères contenant des groupes acétylène et pouvant être réticulés pour produire des polymères hautement résistants et dépourvus de défauts structuraux qu'entraîne généralement la libération de produits volatils au cours de la réticulation.
