Abstract
A great amount of interest has been shown by many investigators on the subject of Benzoylhydrazine derivatives formed by the action of Benzoylhdrazine upon the hexoses. |E. Davides has used the name of benzosazone to describe a class of compounds which are formed from Benzoylhydrazine and aldose in alcohol solution, and which probably contains four molecules of benzoylhydrazine for one molecule of sugar (1). The production of such compounds would demand a very extensive oxidation of the sugar molecule, and would be somewhat of a contradiction to the structure of phenylosazone, which has been carefully investigated a great many times. There is some doubt, therefore, as to the correctness of Davides' research. |Pinkus has questioned the results of Davides' work because Davides carried the reaction between the sugar and the hydrazine in the basic solutions at high temperature.
