To study the effects of the structure of 35 compounds on the life span of L1210 leukemia bearing mice,35 aroyl compounds have been calculated by the CNDO/2 quantum chemistry method.

In order to find new lead compounds,9 novel and one known 1-pyrazol-5′-yl carbonyl-2-substituted benzoylhydrazides were prepared by a condensation reaction of 4-substituted-3-ethyl-1-methyl-5-pyrazole formhydrazide and substituted benzoyl chloride,and their structures were confirmed by()~1H NMR,MS,IR and elemental analysis.

Nine aryl aroyldiazenes were synthesized under mild conditions with short reaction time and excellent yield using dioxane·NO_2 as new oxidant.

Ten aryl aroyldiazenes have been synthesized in excellent yields under room temperature using active manganese dioxide on acidic silica gel as the oxidant.

Synthesis and Characterization of Acyldiazenes Compounds;

The synthesis of a series of acyldiazenes compounds from home made adipyl dihydrazide by using the oxidation system NBS/pyridine was realized.
