Abstract: Method for producing tertiary phosphines by reacting a compound of the general formula (I) in which A is R 1 or L 2 , B is R 2 or L 3 , the R 1 and R 2 radicals are each independently an organic radical having in each case from 1 to 30 carbon atoms, where the R 1 and R 2 radicals may also be joined together; and the leaving groups L 1 to L 3 are each independently halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms (a) with an alkali metal in an organic aprotic solvent and (b) a compound of the general formula (II) L 4 -R 3 (II) in which the R 3 radical is an organic radical having in each case from 1 to 30 carbon atoms; and the leaving group L 4 is halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms, in which the resulting reaction mixture is hydrolyzed with an aqueous base which has a pH of >= 10 and the organic phase is removed from the aqueous phase.

Abstract: A process for the preparation of acylphosphines formula (1) wherein m is 1 or 2; R 1 , R 2 , and R 3 are organic residues derived from aliphatic or aromatic hydrocarbons; by (1) reacting organic phosphorus halides of formula (II) wherein Y is Br or Cl,with an alkali metal in a solvent in the presence of an activator, wherein the alkali metal is present in the form of a dispersion of alkali metal particles having a mean particle size of 1 , R 2 and R 3 are independently from each other phenyl, naphthyl and bi-phenyl, being unsubstituted or substituted by one to five halogen, C 1 -C 8 alky and/or C 1 -C 8 alkoxy. Most preferably, R 1 and R 3 are phenyl and R 2 is 2,4,6-trimethylphenyl. The alkali metal is preferably sodium, the activator is preferably chlorobenzene and/or n-butanol.
