Reference of 1122-61-8, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1122-61-8, name is 4-Nitropyridine. A new synthetic method of this compound is introduced below.
General procedure: A solution of complex 4a (1 g, 4.25 mmol) in benzene (10 ml) was stirred at 15-20 and treated with a solution of heterocyclic amine or oxaadamantane () (4.25 mmol) in benzene (5 ml) (Scheme 10, Table 1). The reaction mixture was stirred for the indicated time at room temperature, with periodic control of the amount of evolved THF by GLC (60-70, adsorbent – chromosorb, liquid phase – PEG monolaurate). After the increase of THF signal stopped, the reaction mixture was evaporated from Petri dish under exaust hood, the residue was extracted first with hexane and then with Et2O. The combined extract was evaporated under vacuum at room temperature, the residue was recrystallized from Et2O-hexane mixture. Complexes of trinitromethylborane with amines (compounds 7-s) or with oxaadamantanes (compounds 4d,e) were thus obtainecharacteristics, as well as yields and melting points of target complexes 4d,e and 7-s are given in Table 1
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1122-61-8, its application will become more common.
