Abstract

A process for producing chromenes intended for the preparation of thermosetting resins, includes converting an aromatic propargyl ether of general formula (I) into a chromene by homogeneous catalysis with copper salts in anisole at a temperature between 100 and 170° C. Moreover, a process for preparing a material made of thermoset resin, includes successively a) carrying out the above process; b) polymerizing the reaction product obtained in a) so as to obtain the material made of thermoset resin; c) recovering the material made of thermoset resin obtained in b).
