Abstract

PROCEDIMIENTO DE OBTENCION DE TIOLES. RESPOMDEN A LA FORMULA GENERAL (I) EN LA QUE CUANDO A ES UN RADICAL HIDROXI-2-OXO-1 ETANILO-1 ILIDENO-2, R ES UN RADICAL QUE SE ELIGE ENTRE: UN ALCOHOL PROTEGIDO CON RADICALES DIMETIL-2,2, DIOXOLANIL-4, METILO O DIMETIL-2,2, DIOXANILO-5, O UN ALQUILO SUSTITUIDO, O UN RADICAL DE FORMULA GENERAL (IIIA) EN LA QUE ALK ES UN RADICAL ALQUILEO, XA E YA SON IDENTICOS Y REPRESENTAN ATOMOS DE OXIGENO O DE AZUFRE, Y RA REPRESENTA UN RADICAL ALQUILO O ALQUILENO. Y CIANDO A REPRESENTA UN RADICAL ALQUILOXICARBONILMETINA R SE ELIGE ENTRE LOS RADICALES ANTES MENCIONADOS. PARA SU OBTENCION SE HACE REACCIONAR UNA TIOSEMICARBAZIDA DE FORMULA GENERAL (II) CON UN DERIVADO DEL ACIDO OXALICO DE FORMULA GENERAL (IV) EN QUE XB E YB REPRESENTAN ATOMOS DE CLORO O RADICALES ALQUILOXI. LA REACCION SE LLEVA A CABO EN PRESNECIA DE UN ALCOHOLATO ALCALINO. POSTERIORMENTE SE PASA A SEPARAR LOS PRODUCTOS OBTENIDOS; ELIMINANDO, EN OCASIONES, LOS RADICALES PROTECTORES.
