Abstract

Procedimiento para la preparación de bisepóxidos, caracterizado porque se hace reaccionar un dieno conjugado de la fórmula general (1), en donde: R1 es seleccionado entre hidrógeno y alquilo C1-12, sustituido o no sustituido con uno o más grupos S-H- u O-H, en presencia de un catalizador, que se puede obtener poniendo en contacto, por lo menos un compuesto de manganeso, elegido entre A2MnX4, AMnX3, MnY, MnX2 y MnX3 con por lo menos un ligando L de la fórmula general (2), definiéndose las variables como sigue: X es igual o diferente y seleccionado entre aniones monovalentes; Y un anión bivalente; A seleccionado entre un metal alcalino y amonio, que puede ser alquilado; R2 son diferentes o preferentemente iguales o seleccionados entre alquilo C1-20; y por lo menos un coligando, derivado de ácidos monocarboxílicos, ácidos carboxílicos bi- o polivalentes o diaminas, con por lo menos un peróxido, usándose hasta 4 equivalentes de peróxido por equivalente de un doble enlace C-C. Obteniéndose así, mezclas de ditiol que contienen de 55 a 65 moles % de evitro ditiol y 35 a 45 moles % treo-ditiol utilizadas para el tratamiento de pieles de animales muertos para eliminar sustancias córneas de las mismas.
