Abstract

Patente de Invenção:<B> PROCESSO PARA ENXERTAR UM GRUPAMENTO DIFLUOROMETILA SUBSTITUìDO"<D>. A invenção se refere a um processo para enxertar um grupamento difluorosubstituído sobre um composto comportando pelo menos uma função eletrófila, compreendendo as etapas que consistem em : i) colocar esse composto que comporta pelo menos uma função eletrófila em presença de um reagente nucleófilo, compreendendo: a) um ácido fluorocarboxílico de fórmula Ea- CF~ 2~-COOH, na qual Ea representa um átomo ou um grupo eletroatraente, pelo menos parcialmente salificado por um cátion orgânico ou mineral, e b) um solvente aprótico polar; e ii) expor o meio reacional à ação de microondas. Esse processo permite notadamente formar ácidos sulfínicos ou sulfónicos fluorados.
