PROCESS FOR PREPARING 2,3-DIHYDRO-2,2-DIMETHYLBENZOFURAN-7-N-/N,N-DISUBSTITUTED AMINOSULPHENYL/-N-METHYLCARBAMATE

摘要

Aminosulphenyl cpds. of formula R1R2NSCl (I) are new. R1 and R2 are X.COOR3 or YCN, or R2 can also be 1-8C alkyl, 3-6C cycloalkyl, phenyl or benzyl (both opt. substd. by halo, or 1-3C alkyl or alkoxy or ZR4. X and Y as 1-6C alkylene. R3 is 1-8C alkyl or 3-6C cycloalkyl. Z is carbonyl or sulphonyl. R4 is 1-6C alkyl, phenyl (opt. substd. by halo or 1-3C alkyl or alkoxy)or phenoxy. - (I) are prepd. e.g. by reacting R1R2NM with sulphur mono- or di-chloride. - (I) are intermediates for cpds.
