With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4733-39-5,2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline,as a common compound, the synthetic route is as follows.
General procedure: 1a-j were prepared photolytically using a procedure adapted from the literature;[25] the synthesis of 1j is presented below and typifies all such syntheses performed in this work. W(CO)6(0.550 g, 1.56 mmol) was dissolved in 50mL dry tetrahydrofuran(Pharmco) and degassed in a round-bottom flask. The resulting solution was illuminated with a 100-W mercury arc lamp until nearly complete conversion to W(CO)5(THF) had been effected[26] as determined by infrared spectroscopy; this normally required 3 to 4 h of constant illumination. To the resulting yellowish-green solution was added a slight molar excess of dmp (0.347 g, 1.64 mmol) under constant stirring and nitrogen purging; this resulted in a rapid colour change and eventual precipitation of the desired product. After 30 min, the precipitate was isolated and washed with additional THF; the crude product was purified by recrystallization from dichloromethane/hexanes. The product (0.516 g, 1.02 mmol, 65%yield) consisted of brick-red crystals and its identity was confirmed by IR spectroscopy. Most of the compounds synthesized exhibited deep-red luminescence as solids.
4733-39-5, The synthetic route of 4733-39-5 has been constantly updated, and we look forward to future research findings.
