PROCESS FOR PRODUCING TERTIARY PHOSPHINE HAVING BULKY HYDROCARBON GROUP BONDED |
摘要 |
<p>The present invention provides a production process by which tertiary phosphine with an attached sterically bulky hydrocarbon group, said tertiary phosphine being useful as a ligand of a transition metal catalyst in organic synthesis reactions, can be produced in a high yield and with high purity on an industrial scale through simple and safe operations. The present invention comprises 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) : <CHEM> 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.</p> |
