Sobre IBD

O trabalho apresentado nesta dissertação diz respeito ao estudo da atividade dos suportes fosfatados sob irradiação por micro-ondas na síntese de produtos de elevado valor acrescentado.Ao longo deste trabalho, constatámos que a desproteção dos 1,1-diacetatos foi facilmente realizada na presença de apatitas dopadas sob micro-ondas.Constatámos que o fosfato natural dopado com cloreto de zinco e ativado por micro-ondas se revelou eficaz na síntese de tioacetais.Por fim, a síntese das α,α’-bis(benzilideno)cicloalcanonas foi realizada com bons rendimentos em tempos muito curtos, graças à ação catalítica da fluorapatita dopada com nitrato de sódio e ativada por micro-ondas.
