arenediazonium tetrafluoroborates and maleimides in the presence of TiCl3. The reactions generated 3-arylsuccinimides in satisfactory yields under mild reaction conditions. In addition, 3-arylmaleimides were obtained by the coupling of arenediazonium tetrafluoroborate and maleimides catalyzed by CuCl. This methodology provided the selective and tunable synthesis of two classes of products by simply
An acrylic modified styrenic/N-arylmaleimide copolymer containing composition whith exhibits excellent melt flow properties, impact strength and gloss upon moulding is obtained by (A) polymerising at least one alkyl acrylate monomer in the presence of at least one polyfunctional acrylate crosslinking monomer; (B) forming a styrenic/N-arylmaleimide/1,3-diene terpolymer in the presence of the crosslinked polyacrylate prepared in (A); and (C) forming a styrenic/N-arylmaleimide copolymer in the presence of the crosslinked polyacrylate prepared in (A) and the styrenic/N-arylmaleimide/1,3-diene terpolymer prepared in (B).

The Heck reaction of maleimides with aryl iodides in the presence of PdCl2(MeCN)(2), Bu4NCl and HCOOK affords the corresponding 2-arylmaleimides in moderate yields.
