Synthesis method of polyphenylpyridine nitrate

The invention belongs to the technical field of organic synthesis, and relates to a synthesis method of polyphenylpyridine nitrate. The synthesis method comprises the following steps of: (1) synthesizing 2, 4, 6-triphenylpyran perchlorate; (2) synthesizing 1, 3, 5-triphenyl-2-pentane-1,5-dione (3) synthesizing 2, 4, 6-triphenylpyran nitrate; and (4) synthesizing the 1, 2, 4, 6-tetraphenylpyridine nitrate. By utilizing the synthesis method of the polyphenylpyridine nitrate, the polyphenylpyridine nitrate can be efficiently synthesized by adopting a method of cyclizing aminobenzene and diketone through reaction, the selectivity is strong, the side reaction is less, the yield is higher, the process conditions are relatively mild, and the adopted raw materials are simple and easy to obtain.

Catalytic activity of Mg-Al hydrotalcites and derived mixed oxides for imination reactionsviaan oxidative-dehydrogenation mechanism

The catalytic activities of Mg-Al hydrotalcites and derived Mg-Al mixed oxides were studied for the imination of benzylic substrates (benzyl amine and benzyl alcohol), with aniline as a model reaction, to establish a green and cost-effective catalytic (precious metal free) process for imination and tandem reactions utilizing alcohols as reagents. The Mg-Al mixed oxide (Mg/Al ratio = 3.0) was found to be an efficient catalyst for imination reactions to synthesize cross-imines with high selectivity as well as for tandem reactions of alcohols. Basic sites of catalysts adsorb benzylic substrates through the hydrogen of their functional groups (-NH2/-OH) and activate (weaken) benzylic C-H bonds for hydride elimination. Thus, basic sites catalyze the reaction by activating benzylic substrates for oxidative-dehydrogenation (i.e., deprotonation followed by hydride elimination with the help of oxygen) to produce reactive imine/carbonyl intermediates, which undergo subsequent nucleophilic reactions with amine.
