摘要

The preparation process of fluorescent compounds anhydrides maleicos arilados, acrylates, substituu00ecdos arilados and maleimidas ariladas.The present invention is an efficient process for the preparation of fluorescent compounds anhydrides maleicos arilados, acrylates, replaced arilados and maleimidas ariladas carried out by means of a few steps reacionais, from substrates and reagents are cheap and available comercialm Ente.For the production of these compounds was developed a new protocol of arilau00e7u00e3o heck on the maleic anhydride, maleimidas and acrylates, replaced with a variety of diazonium salts.This new process enabled the production of their compounds mono or bisarilados (symmetrical or non simu00e9trlcos), in one or two stages reacionais, with income variables, depending on the nature of the diazonium salt used and the conditions reacionais.Some of these compounds have pronounced fluorescent properties, which may have promising industrial applications in the grave of optical brighteners, for example.
