Thermostable naphthalate-containing copoly(amide-imide)s with inherent viscosity of 0.53-0.96 dL/g were synthesized by reacting diacid-terminated naphthalate monomers with various diisocyanate-terminated polyimide prepolymers. The polyimide prepolymers were prepared by using 4,4-diphenylmethane diis
UV irradiation of a number of N-alkenyl substituted maleimide and tetrahydrophthalimide derivatives leads to the formation of complex 1azabicyclo[5.3.0]dec-3-enes in excellent yields.
An efficient one-step synthesis of 4-nitro-N-aryl substituted glutarimides, succinimides and maleimides in polyphosphoric acid is described together with the subsequent reduction to the corresponding anilines. The scope and limitation of this cyclocondensation are presented.
