Abstract

LOS AZUCARES Y DERIVADOS DE AZUCARES PARCIALMENTE PROTEGIDOS SE CLORAN POR REACCION DE GRUPOS HIDROXILO SIN PROTEGER CON CLORURO DE TIONILO PARA FORMAR UN PERSULFITO, SEGUIDA DE DESCOMPOSICION DEL GRUPO SULFITO PARA FORMAR CLOROSULFITOS, DESPLAZAMIENTO DE LOS GRUPOS CLOROSULFITO E INSERCION DE LOS ATOMOS DE CLORO EN UNA O MAS POSICIONES, CARACTERIZADA PORQUE LA FORMACION Y DESPLAZAMIENTO DE LOS GRUPOS CLOROSULFITO Y LA INSERCION DE LOS ATOMOS DE CLORO SE EFECTUA POR REACCION CON CLORURO DE TIONILO EN UN DISOLVENTE INERTE EN PRESENCIA DE UNA SAL CUATERNARIA DE FORMLA GENERAL (I), EN DONDE R1, R2 Y R3, QUE PUEDEN SER EL MISMO O DIFERENTES, SON UN GRUPO ALQUILO INFERIOR, Y R4 ES UN GRUPO HIDROCARBONADO CON 7 ATOMOS DE CARBONO POR LO MENOS, Y CUANDO EL AZUCAR O DERIVADO DE AZUCAR PARCIALMENTE PROTEGIDO TIENE MAS QUE 3 GRUPOS HIDROXI NO PROTEGIDOS, EL PROCESO CONSTA DE LAS SIGUIENTES ETAPAS: (A) REACCION DEL AZUCAR O DERIVADO DE AZUCAR PARCIALMENTE PROTEGIDO CON CLORURO DE TIONILO EN PRESENCIADE PIRIDINA PARA FORMAR UN PERSULFITO; (B) SEPARACION DEL PERSULFITO PARA ELIMINAR PIRIDINA LIBRE; Y (C) REACCION DEL POLISULFITO SEPARADO CON CLORURO DE TIONILO EN UN DISOLVENTE O MEDIO DE SUSPENSION INERTE, EN PRESENCIA DE UNA SAL CUATERNARIA DE FORMULA GENERAL (I).
