Novel palladium (II)-containing polyimides with exceptional catalytic properties for the Heck and Suzuki-Miyaura cross-coupling reactions were prepared from Pd(II)-alpha-bis(imine) complex and the corresponding dianhyrides. The glass transition temperatures (T-g) of the polymers ranged from 169 to 241degreesC. The temperatures at which 10% weight loss occurred in air ranged from 415 to 579degreesC. Polyimides based on the palladium (II) complex were tested for catalytic activity in the Heck coupling reaction between styrene and several aryl halides and the Suzuki coupling reaction between phenylboronic acid and several aryl halides. The negative effects (e. g., expense, low reaction rates, air-sensitivity) experienced by using phosphines, particularly electron-rich phosphines, as catalysts in large scale applications is overcome by using polymer supported catalysis.
