Abstract: The present invention relates to a new, selective process for the preparation of mono- and bisacylphosphanes of formula (I) n and m are each independently of the other 1 or 2; R1, if n=1, is e.g. phenyl R1, if n=2, is e.g. C1-C18alkylene or phenylene; R2 is e. g. C1-C18alkyl, phenyl or substituted phenyl; R3 is e. g. C1-C18alkyl, by (1) reacting a phosphorous halide of formula IIa or a phosphorous halide oxide of formula (IIb) or a phosphorous halide sulfide of formula (IIc) with an alkali metal in a solvent in the presence of a proton source; (2) subsequent reaction with m acid halides of formula (III) An oxidation step may follow to obtain mono- and bisacylphosphane oxides or mono- and bisacylphosphane sulfides.

Abstract: The invention relates to a process for the preparation of cycloorganylphosphanes of formula 1 (R1P)n by reaction of dihalo(organyl)phosphanes of formula R1PHal2 with: a) activated zinc in an organic solvent, or with: b) an alkali metal or alkaline earth metal in a non-polar organic solvent in the presence of an activator, wherein R1 is C1–C12alkyl; C3–C12 cycloalkyl, aryl or heteroaryl, Hal is F, Cl, Br or I, and n is a number from 3 to 20. The invention relates also to novel di(alkali metal/alkaline earth metal) oligophosphanediides and to the use thereof in the preparation of organophosphorus compounds.
