Title:
METHOD OF PRODUCING DITHIOL COMPOUND AND CYCLIC DISULFIDE COMPOUND
Document Type and Number:
Japanese Patent JP2013155144
Kind Code:
A
Abstract:
To provide a method of easily producing a dithiol compound in high yield.
A dithiol compound represented by general formula (4) or (5) is easily obtained in high yield by reacting a dihalogen compound with a thiourea compound in water or in a mixed solvent of water and a nonpolar solvent, and then, hydrolyzing an obtained isothiouronium salt in the presence of a base. In the formula: Y is a hetero atom and/or a 1-18C hydrocarbon group wherein a hetero atom or a ring structure is included; and R1, R2, R3 and R4 are the same or different respectively, each representing a hydrogen atom or a 1-4C straight or branched chain alkyl group.
