Abstract
Poly(aminophthalimide) (PAP) dimers and trimers have been synthesized by palladium-catalyzed cross-coupling reactions of 3-aminophthalimides with 3-chloro- and 3,6-dichlorophthalimide, respectively. When Pd(OAc)2, XPhos (2-dicyclohexylphosphino- 20,40,60-triisopropylbiphenyl), and K3PO4 are used, the C–N bond-forming reactions proceed quantitatively. The structures of those oligomers are examined by experimental and theoretical techniques including NMR, IR, single-crystal
