A g-C3N4-based heterogeneous photocatalyst for visible light mediated aerobic benzylic C-H oxygenations

A metal-free heterogeneous photocatalytic system has been developed for highly efficient benzylic C-H oxygenations using oxygen as an oxidant. This visible light mediated oxidation reaction utilizes graphitic carbon nitride (g-C3N4) as a recyclable, nontoxic and low cost photocatalyst. Mild reaction conditions allow for the generation of synthetically and biologically valued isochromannones, phthalides, isoquinolinones, isoindolinones and xanthones from readily accessible alkyl aromatic precursors in good yields. The heterogeneous nature of the g-C3N4 catalytic system enables easy recovery and recycling as well as the use in multiple runs without loss of activity. The synthetic utility of this “green” methodology was further demonstrated by applying in bioactive and drug valued target syntheses.

Some tips on 52010-22-7

The synthetic route of 52010-22-7 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.52010-22-7,4-Chlorophthalide,as a common compound, the synthetic route is as follows.

A 45.85 g sample of an oxidation mixture in acetic acid from the oxidation of 3- and 4-chloroxylene in the presence of a catalyst composition comprising cobalt and manganese was treated with 0.143 g. of oxalic acid dihydrate and brought to reflux for 30 minutes (this process removed about 90% of the cobalt and >50% of the manganese by precipitation as the oxalate salts). The solution was then passed through a glass frit under vacuum. The remainder of the solvent was removed by evaporation (down to 16.2 g.) and distillation (down to 14.0 g. residue). The remaining light yellow solid was combined with 60 ml. of water and 40 ml. of toluene, and mixed. There was some emulsion layer which was treated in a second wash with an additional 15 ml. each of water and toluene. The solvent was removed by evaporation of each fraction to leave 10.6 g. in the water fraction and 2.7 g. in the toluene fraction. The fractions were analyzed by GC. The analytical results are shown in Table 7.
