Palladium‐catalyzed synthesis of bis(phosphinates) and bis(phosphine oxides) with tetra‐ and hexamethylene bridges

Abstract
Some aryl‐substituted bis(phosphinates) and bis(phosphine oxides) with tetra‐ and hexamethylene bridges, which are not easily accessible by conventional chemical methods, were synthesized by palladium‐catalyzed formation of the carbon – phosphorus bond.
