Salts of dithiocarbamic acid which can be converted into isothiocyanates, which are suitable intermediates for producing thiazabicyclononane derivatives and monothiourazole derivatives, in a remarkably high yield; a process for producing the salts in a high yield without the necessity for using thiophosgene which is problematic in toxicity; and a process for producing isothiocyanates from the salts. The salt is a compound represented by general formula (2) and produced by the reaction of an aniline represented by general formula (5) with carbon disulfide in the presence of 1,4-diazabicyclo[2.2.2]octane (3) or 4-pyrrolidinopyridine (4). The isothiocyanate (1) is produced by the reaction of the salt (2) with a halogen compound.
