Popis: | It is reported the synthesis of 24 Morita-Baylis-Hillman adducts (3a-3l/6a-6l) using microwave irradiation at 80 ºC or conventional protocol at 0 ºC to promote the reactions between aromatic aldehydes and methyl acrylate or acrylonitrile (81-99%). It is shown that the reaction of 2-hydroxy(4-bromophenyl)methyl acrylate formation is reversible at 120 ºC. Relatamos a síntese de 24 adutos de Morita-Baylis-Hillman (3a-3l/6a-6l) usando irradiação de microondas a 80 ºC ou protocolo convencional a 0 ºC para promover reações entre aldeídos aromáticos e acrilato de metila ou acrilonitrila (81-99%). Provamos que a reação de formação do acrilato de 2-hidroxi(4-bromofenil)metila é reversível a 120 ºC. |
