Abstract: The invention relates to a process for making an isomeric mixture of secondary phosphines with the summation formula C20H27P. To this end, hydrogen phosphide is reacted with dicyclopentadiene in the presence of an agent yielding free radicals. More specifically, hydrogen phosphide and dicyclopentadiene are used in a molar ratio of 1 to at least 2 and the reaction is effected under a pressure of 5 to 90 bars. The mixture is used in the production of flotation aids and as an ingredient of catalytically active transition metal complexes.

Abstract: The invention relates to a process for making tertiary phosphines of the general formula R3P, in which R stands for a linear alkyl radical having 2 to 4 carbon atoms. To this end, hydrogen phosphide is reacted with linear monoolefins having 2 to 4 carbon atoms. More particularly, the tertiary phosphine which is desired to be made is dissolved in an inert solvent and PH3 and monoolefin are reacted in the solution.
