14172-91-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II), cas is 14172-91-9,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
General procedure: Under the protection of nitrogen, 0.14 mmol of the corresponding 5,10,15,20-tetrakis(4-R-phenyl)porphyrin copper(II)complex was dissolved in 16 ml of CHCl3, to which 0.75 ml of DMFwas added with magnetic stirring. The solution was cooled to 0 Cin an ice bath, and then 0.56 ml of phosphoryl chloride (POCl3) wasslowly added within 20 min. The ice bath was removed and stirringwas continued at room temperature for 1 h, and the solution wascontinuously stirred and heated at 70 C for 24 h. Then 3.606 g ofNaAc and 14.4 ml of distilled water were added in an ice bath andstirring for another 1 h. After separation of the aqueous layer, theorganic layer was washed with 10 ml of distilled water for 3 times,then dried over anhydrous magnesium sulfate and filtered. Thesolvent was removed by rotary evaporation at low temperature toafford a crude product. The crude product was dissolved indichloromethane and subjected to column chromatography overneutral alumina with dichloromethane/petroleum ether (v/v 3:1)as the eluent. The third coloured bandwas collected and the solventwas removed by rotary evaporation to afford a purple powder.
The chemical industry reduces the impact on the environment during synthesis,14172-91-9,5,10,15,20-Tetraphenyl-21H,23H-porphine copper(II),I believe this compound will play a more active role in future production and life.
