Synthesis and characterization of Dithia[3.3](2,6)pyridinophane-containing polymers: application to the palladium-catalyzed Heck reaction.
[reaction: see text] We synthesized zigzag polymers consisting of dithia[3.3](2,6)pyridinophane units that were flipped rapidly as a result of syn-[anti]-syn isomerization. Pyridinophane units were fixed in the syn form by complexation with palladium, and the resulting polymer complex exhibited a high catalytic activity for the Heck coupling reaction.
