REACTION OF 2-HETEROSUBSTITUTED BENZOTHIAZOLES WITH ALLYLIC GRIGNARD REAGENTS

Article abstract of DOI:10.1016/S0040-4020(01)98829-5

The title benzothiazoles 1 react with allylic Grignard reagents affording 2-allylbenzothiazoles 5, 2,2-diallylbenzothiazolines 6 and N-triallylmethyl-o-aminobenzenethiols as disulphides 7 depending upon the experimental conditions.The reaction is considerably influenced by the solvent used and the nature of the allylic Grignard.A possible mechanism for the formation of compounds 5, 6 and 7 is reported.
