Synthesis method and application of amide crystal compound

A synthesis method of an amide crystal compound (I) with the following structural formula and unit cell parameters comprises the following steps: under water-free and oxygen-free conditions, weighing2.0968g of benzophenone hydrazone and 1.9990g of copper acetate monohydrate, putting the raw materials into a 250mL two-neck flask, adding 100mL of chlorobenzene as a solvent, carrying out reflux reaction for 48 hours, carrying out column chromatography separation, carrying out eluting with petroleum ether/dichloromethane (3/7), and naturally volatilizing a collected first component point to obtain single crystal N-acetylamino benzophenone hydrazone. According to the application of the amide crystal compound (I), a certain catalytic effect is shown in the self-condensation reaction of benzophenone imine as a catalyst, and the conversion rate of benzophenone imine reaches 53%.

Microwave assisted solvent-free C-H amination by silica-supported manganese dioxide

An effective and convenient method has been developed for the preparation of 1-unsubstituted 1H-indazoles via C-H amination of N-acetylhydrazones in the presence of a catalytic amount of manganese dioxide under microwave irradiation. This new method featured easy operation and relatively short reaction-time.

NOTES ON THE REACTIONS OF KETONE ACYLHYDRAZONES UNDER ACYLATION CONDITIONS

The reactions of the acetophenone and fluorenone acylhydrazones under acylation conditions were investigated.The structures of the diacylhydrazones and 1,3,4-oxadiazolines formed were proved by UV, IR, (1)H- and (13)C-NMR spectroscopical as well as by MS
