| Research Abstract |
The purpose of the present study was to develop palladium-catalyzed synthetic reactions and to elucidate their reaction mechanisms.
1 Derivatives of 2-butyne-1, 4-diol were carbonylated in ethanol in the presence of Pd-phosphine catalyst. Its carbonate of ethyl chloroformate gave bis(methylene)butanedioate in a high yield.
2 Thienyl-substituted 2-butyne-1, 4-diols were carbonylated in benzene in the presence of palladium acetate and iodine to give photochromic bisthienylfulgides in one-pot.
3 Palladium- and copper-catalyzed copolymerizations of carbon monoxide with ethylene or styrene were investigated. Pyrolysis-GC revealed that the polymers obtained were of alternating structures.
4 Allylation of pronucleophiles, and telomerization and cocyclization of buta-diene were investigated under neutral conditions. Their reaction mechanisms were discussed from a viewpoint of amphiphilic nature of the bis-π-allylpalladium intermediate.
5 Styrenes, stilbenes, and poly(phenylene vinylene)s were synthesized by the Heck reaction of ethylene with haloarenes.
