    Abstract: 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.

    Abstract translation: 通过简单且安全的操作,通过使二烷基膦卤化物与格氏试剂在铜的存在下反应,通过简单且安全的操作,以高产率和高纯度产生具有附着的空间体积烃基的叔膦的生产方法 化合物的量相对于二烷基膦卤化物为0.1〜5摩尔%,以制备由下式(3)表示的叔膦:其中R 1和R 2, 各自为4〜13个碳原子的叔烃基,R 3为烷基,烯基,芳基等。
