Abstract

"PROCESSO DE PREPARAçãO DE UM TRIFLUOROMETIL TIOéTER". Processo para a preparação de um trifluorometil tioéter da fórmula (I) pela reação de um tiocianato da fórmula (II) com um haleto de trifluorometila na presença de um sistema de redução compreendendo um sal ditionita ou um sal hidroxi metano sulfinato compreendendo um, quinze ou mais agentes de redução com o dióxido de enxofre."PROCESS FOR PREPARING A TRIFLUOROMETIL THIOether". A process for preparing a trifluoromethyl thioether of formula (I) by reacting a thiocyanate of formula (II) with a trifluoromethyl halide in the presence of a reducing system comprising a dithionite salt or a hydroxy methane sulfinate salt comprising one, fifteen or more reducing agents with sulfur dioxide.
