CHLORURES D'AMINOSULFENYLE, PROCEDE POUR LEUR PREPARATION ET LEUR UTILISATION DANS LA PREPARATION DE CARBAMATES POSSEDANT DES PROPRIETES INSECTICIDES, MITICIDES OU NEMATOCIDES

摘要

An aminosulfenyl chloride derivative represented by the formula (I): (I) wherein R1 and R2 are defined in the specification, which is useful as an intermediate for the preparation of a carbamate derivative represented by the formula (III): (III) wherein R1 and R2 are the same as defined above, the carbamate derivative having an insecticidal, miticidal or nematocidal activity, is disclosed. A process for preparing the aminosulfenyl chloride of the formula (I), and a process for preparing the carbamate derivative of the formula (III) using the aminosulfenyl chloride of the formula (I) are also disclosed.
