hydrazone

The tautomeric equilibrium between the azo type and the hydrazone type of these compounds in different solvents and different acidity has also been studied.

对它们在不同溶剂。不同酸碱度溶液中的偶氮式及式间互变异构平衡进行了研究。

The two now isonicotnic acid hydrazone and N-oxide isonicotinic acid hydrazone of ethyl furoyl acetates were synthesised. The condensations were carried out in ethyl alochol medium.
