    Abstract: SE REFIERE A UN PROCESO PARA LA CONVERSION DE UNA N-HIDROXILAMINA EN UNA N-HIDROXIFORMAMIDA CON FORMATO DE 2,2,2-TRIFLOROETILO EN UN SOLVENTE TAMPONADO A UNA TEMPERATURA DE 50°C A 70°C DURANTE 3 HORAS A 24 HORAS. LA N-HIDROXILAMINA SE SELECCIONA DE N-BENCIL-N-HIDROXILAMINA, (1S)-1-(N-HIDROXIAMINO)ETIL)BENCENO, 3-((2S)-2-(N-HIDROXIAMINO)-3-((4'-(TRIFLOROMETOXI)(1,1'-BIFENIL)-4-IL)OXI)PROPIL)-5,5'-DIMETIL-2,4-DIMETIL-2,4-IMIDAZOLIDINDIONA, ENTRE OTROS. EL TAMPON SE SELECCIONA DE UNA SAL CARBONATO, SAL BICARBONATO, SAL FOSFATO, ENTRE OTROS DE PREFERENCIA EL GRUPO IMIDAZOL Y UNA SAL CARBOXILATO O FORMATO DE SODIO. EL SOLVENTE SE SELECCIONA DEL GRUPO TETRAHIDROFURANO, ETER DE METIL TER-BUTILO, ENTRE OTROS DE PREFERENCIA ACETATO DE ISOPROPILO, ETER DE METIL TER-BUTILO
