As part of this overall program, the authors were interested in preparing the ac.lated der:vatives of BZ. In this connection attempts were made to acetylate BZ with acetic anhydride and wth acetyl chloride ia pyridine to no avail. The infrared spectrum of BZ indicates strong intramolecula.. vr intermolecular hydrogen bonding, which is absent in its %salts. The tionreactivity observed with the usual acetylating reagents may be due to this bonding as well as to steric factors. Thus, treatment of the p-toluentsulfonic acid *Idt of BZ with 3sopropenyl acetate afforded the acetate quite smoothly.

Body of Abstract
(C) The purpose of this work was to conduct a fundamental study of the chemistry of BZ. to assist in problems that may arise in detection. decontamination, biochemical mechanism of action, and metabolism. BZ reacts with (0? substituted phenyl ssocyanates to yield. 2.4-oxazolidinediones. (2)nitriles to produce amrides (Ritter reaction). and (3) alkyl halides to give quaternary ammonium salts. Analysis of BZ can be accomplished by quaternization in acetonitrile. separation uf reactants, and assaying spectrally.
