With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.719-80-2,Ethoxydiphenylphosphine,as a common compound, the synthetic route is as follows.
719-80-2, 2.06 grams (7.84 mmol) of 2-(4-fluoro-3-methyl-phenyl)-4,6-dimethylbenzyl chloride was treated with ethyldiphenylphosphinite (2.08 grams, 9.01 mmol) and heated to 150 C. for 3 hrs. After cooling to room temperature, the crude mixture was purified by silicagel chromatography ((10% acetone/90% methylene chloride) and the appropriate fractions concentrated and recrystallized from ether/hexane to provide the title compound (MP 109-111 C.).
719-80-2 Ethoxydiphenylphosphine 69754, achiral-phosphine-ligands compound, is more and more widely used in various fields.
