| 摘要 |
<p>The present invention relates to a method for preparing a tertiary phosphine, or derivatives thereof, of general formula (I): PR3 (I) wherein each of the R groups, identical or different, is chosen from an alkyl group, a cycloalkyl group, an alkyl(cycloalkyl) group, a cycloalkyl(alkyl) group, an -SiR1R2R3 group or an -SnR1R2R3 group, wherein each of the R, R2 and R3 groups, identical or different, includes an alkyl, cycloalkyl, alkyl(cycloalkyl) or cycloalkyl(alkyl) group, each of the R, R1, R2 and R3 groups optionally being substituted, said method comprising at least one step consisting of reacting, in an inert atmosphere and in an aprotic organic solvent, white phosphorous, P4, with a halide or a pseudo-halide R-X, where X is a halogen atom or a pseudo-halogen group and R is as previously defined, in the presence of a reducing reagent consisting of, or comprising, an alkali metal with a degree of oxidation of 0.</p> |
