Abstract

The invention relates to a method for the manufacture of substituted phosphanes and substituted phosphanes manufactured according to the method. Phosphanes, phosphane oxides, sulfides or selenides are used as ligands in coordination compounds. They play a central role in controlling the activity and selectivity of catalysts. The object is achieved by the invention by synthesizing heterocyclic substituents on aromatic groups by introducing acetyl groups. In this manner, previously unknown representatives of the families of phosphanes, phosphane oxides, sulfides and selenides are made accessible.
