Chemistry Department, University of Roorkee, Roorkee Manuscript received 23 November 1979, revised 14 .August 1980, accepted 29 October 1980 Some new series of hydrazono derivatives of 2-aminobenzothiazoles were synthesised. 2-aminobenzothiazoles were diazotised and then coupled with reactive methylene compounds viz., 2,4-pentanedione, ethyl-2-eyanoethanoate and 5,5-dimethylcylohexane 1,3-dione in presence of sodium acetate. The three series of compounds are expected to possess remarkable biological activity
