A production process by which tertiary phosphine with an attached sterically bulky hydrocarbon group is produced in a high yield and with high purity on an industrial scale through simple and safe operations by allowing a dialkylphosphinous halide to react with a Grignard reagent in the presence of a copper compound in an amount corresponding to 0.1 to 5% by mol based on the dialkylphosphinous halide to produce tertiary phosphine represented by the following formula (3):
wherein R1 and R2 are each a tertiary hydrocarbon group of 4 to 13 carbon atoms, and R3 is an alkyl group, an alkenyl group, an aryl group or the like.
通过简单安全的操作,使二烷基膦卤化物在铜化合物的存在下与格氏试剂反应,产生带有立体障碍的烷基羟基磷酰胺,从而在工业规模上高产高纯地生产三级磷化物,所述铜化合物的用量相当于基于二烷基膦卤化物0.1至5%的摩尔比,所述三级磷化合物由以下式(3)表示:其中R1和R2均为4至13个碳原子的三级烃基,而R3为烷基,烯基,芳基或类似基团。
