Abstract
"MéTODO SINTéTICO PARA A FLUORMETILAçãO DE áLCOOIS". Um método para fluormetilar álcoois halogenados. O método inclui a etapa de proporcionar um álcool alfa-halogenado da fórmula R^ 1^ (CX~ 3~)~ 2~OH, em que R^ 1^ é selecionado a partir do grupo consistindo de hidrogênio e de grupos alquila. O álcool alfa-halogenado é reagido com um primeiro composto da fórmula CH~ 2~ (OR^ 2^)~ 2~ na presença de um catalisador ácido para formar um acetal. O acetal resultante é então clorado com um agente de cloração para formar um composto de cloreto da fórmula R^ 1^C (CX~ 3~)~ 2~OCH~ 2~C1. O composto de cloreto é então convertido a um composto de fluoreto da fórmula R^ 1^C (CX~ 3~)~ 2~OCH~ 2~F usando um agente de fluoração.
