CA 2717063

Disclosed is a novel method for producing a corresponding isothiocyanate compound having a carboxyl group from an amino compound having a carboxyl group. Specifically disclosed is a method for producing an isothiocyanate compound having a carboxyl group and represented by formula (2), wherein an amino compound having a carboxyl group and represented by formula (1) (wherein A represents a C6-14 aromatic hydrocarbon group, a C1-12 saturated hydrocarbon group or the like, and B represents a single bond, a C6-14 aromatic hydrocarbon group, a C1-12 saturated hydrocarbon group or the like) is reacted, in a solvent, with carbon disulfide (CS2) and then with a halogen as a simple substance. (1)(2)

L'invention porte sur un nouveau procédé de fabrication d'un composé isothiocyanate correspondant ayant un groupe carboxyle à partir d'un composé amino ayant un groupe carboxyle. De façon spécifique, l'invention porte sur un procédé de fabrication d'un composé isothiocyanate ayant un groupe carboxyle et représenté par la formule (2), où un composé amino ayant un groupe carboxyle et représenté par la formule (1) (dans laquelle A représente un groupe hydrocarboné aromatique en C6-14, un groupe hydrocarboné saturé en C1-12 ou similaires, et B représente une simple liaison, un groupe hydrocarboné aromatique en C6-14, un groupe hydrocarboné saturé en C1-12 ou similaires) est mis à réagir dans un solvant, avec du disulfure de carbone (CS2), puis avec un halogène comme substance simple.
