Abstract

LOS DERIVADOS DE TIOFENO CON UN GRUPO AMINO (SUSTITUIDO EN SU CASO) EN EL ANILLO TIOFENO SE OBTIENEN POR DEHIDRACION DE DIHIDROTIOFENOS (SUSTITUIDOS DE LA MISMA FORMA QUE LOS DERIVADOS DE TIOFENO DESEADOS) CON H2O2, HACIENDO REACCIONAR EN UN PRIMER NIVEL LOS DIHIDROTIOFENOS CON H2O2 EN UN MEDIO NEUTRAL HACIA LOS SULFOXIDOS CORRESPONDIENTES QUE SE TRANSPONDRAN EN EL SEGUNDO NIVEL DE REACCION CON ACIDO A LOS DERIVADOS DE TIOFENO. LOS DIHIDROTIOFEN - 1 - OXIDOS FORMADOS COMO PRODUCTOS INTERMEDIOS SON NUEVOS COMPUESTOS. SON - DE LA MISMA FORMA QUE LOS DERIVADOS OBTENIDOS DE ELLOS POR TRASPOSICION CON ACIDO - PRODUCTOS INTERMEDIOS PRINCIPALMENTE EN EL SECTOR DE FITOPROTECTORES Y FARMA.
