855-38-9, Tris(4-methoxyphenyl)phosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,855-38-9
1a (70.5 mg, 0.20 mmol), 4-phenylthioxanthone (3 mg, 0.01 mmol), CH3OH (30 mL) were added to a pyrex reaction flash which was equipped with a magnetic stirrer. The mixture was irradiated by a 23 W household lamp at rt under air atmosphere. The photoreaction was completed after 40 minutes as monitored by TLC (eluent: petroleum ether). The solvent was removed and the residue was purified by flash column chromatography on silica gel (eluent: petroleum ether/ethyl acetate = 10/1?EA) to afford 2a as a solid (74 mg, 100%); 1H NMR (400 MHz, CDCl3) delta 7.56 (dd, J = 11.6, 8.8 Hz, 6 H), 6.95 (dd, J = 8.8, 2.0 Hz, 6 H), 3.83 (s, 9 H).
The synthetic route of 855-38-9 has been constantly updated, and we look forward to future research findings.
