Abstract
This laboratory deals with the chemistry of hydrazines and hydrazones particularly those derived from carbohydrate molecules continuing this interest the work of this thesis deals with the chemistery of some hydrazones that are attached to 1.2.4 triazine rings this interest has been aroused from the fact that compounds containing the 1.2.4 triazine moiety are found in natural materials and some of these show biological activity a large number of synthetic 1.2.4 trizines also have biological activity and been used for various purposes.
