| Outline of Final Research Achievements |
During the course of our study on searching suitable heterogeneous Pd catalysts for the synthesis of 1,3-butadiene-containg cross-conjugated polymers, we have found that Pd/C is a good catalyst for direct arylation polycondensation. We also found that transformation of 1,3-butadiene-containg cross-conjugated polymers, which were synthesized by the Pd(0)-catalyzed cross-coupling polymerization of a propargylic biscarbonate with aryl diboron compounds, into the corresponding cyclohexadiene-containing conjugated polymers succeeded through the Diels-Alder reaction with dimethyl acetylenedicarboxylate. Aromatization of the cyclohexadiene skeleton was made by use of DDQ to give the o-phenylene-based conjugated polymers. 2,3-Diphenyl-1,3-butadiene with dienophiles proceeded more efficiently in DMSO than in 1-chloronaphthalene. The results suggest that s-cis conformation-based reaction would proceed more efficiently in DMSO than in 1-chloronaphthalene.
