4020-99-9, Name is Methoxydiphenylphosphine, molecular formula is C13H13OP, belongs to chiral-phosphine-ligands compound, is a common compound. In a patnet, once mentioned the new application about 4020-99-9, Safety of Methoxydiphenylphosphine
The present invention provides a synthetic 1-benzyloxy-2 – [2 – (3-methoxyphenyl) vinyl] phenyltheophylline method, the molar ratio of 1 : 1.05-1.15 diphenyl methoxy phosphorus and between the added to the reaction apparatus for making, to elevate temperature under stirring condition 55-60C, and at this temperature the reaction 8-12h, after the reaction is cooled to room temperature, between to benzyl diphenyl phosphorusoxychloride; benzyl diphenyl phosphorusoxychloride in the solvent and basifier added, to control the temperature to 10-20C, continue to dripping solvent; in 10-20 C lower heat insulating 6-10h; pressure reducing and recovering the solvent to dry, add water to stir and after-filtration; material water to neutral, for 55-60 C drying to obtain the 1-benzyloxy-2 – [2 – (3-methoxyphenyl) vinyl] benzene. The above-mentioned synthetic preparation method is simple, and the mild reaction, it is easy to realize. (by machine translation)
