| titleOfInvention | The preparation method of Isothizole derivatives |
| abstract | The invention provides that a kind of formula (3) represents 3, the preparation method of 4-bis-chloro-5-cyano group isothiazole, it is characterized in that, make general formula (1) (in formula, n represents the integer of 0 ~ 2) sulfur subchloride that represents of the nitrile compound that represents and general formula (2) (in formula, m represents the integer of 1 ~ 2) reacts in aprotic polar solvent.There is provided a kind of not containing the preparation method of high 3, the 4-bis-chloro-5-cyano group isothiazole of the purity of tar ingredients thus, the method yield is high, effective and do not use the raw material of strong toxicity, and suppresses waste to produce, can easy enforcement at industrial scale.n Sn m Cln 2 (2) |
