    摘要: 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.
