The ene reaction between maleimides and allyl-substituted aromatics

Abstract

The products from the 'ene' reaction between allyl-substituted aromatics and maleic anhydride, maleimide, N-phenylmaleimide and N-(4-phenoxyphenyl)maleimide have been isolated and characterised, and a semi-quantitative assessment of ene and enophile reactivities has been made. The reaction between N-phenylmaleimide and allylaromatics bearing a 1,3,5-triazine substituent has been investigated as a model for a proposed cyanate ester-bis-maleimide-allyl cyanate ester ter-polymerisation.
