Some reactions of 3-diazo-1-methyl-2-p-tolylsulphonyliminoindoline and of 2-arylsulphonylimino-1-methylindolines

Abstract

The reactions of 3-diazo-1-methyl-2-p-tolylsulphonyliminoindoline with triphenylphosphine and with a variety of acids have been examined; the compound is less reactive than 3-diazo-1-methyloxindole. The methylene group of a 2-arylsulphonylimino-1 -methylindoline is reactive; condensation products are formed with p-nitrosodi-methylaniline and with a variety of aromatic aldehydes.
