Abstract
Abstract1,4‐Diphosphabarrelenes are bicyclic diphosphines relevant, for example, for the generation of polymetallic coordination compounds. However, current synthetic protocols either suffer from low yields or require multiple reaction steps. Herein, we report the one‐step synthesis of pyrrole‐based 1,4‐diphosphabarrelenes that are obtained in very good yields from the reaction of 1,2,5‐trimethylpyrrole with 1,2‐bis(dichlorophosphino)ethane or 1,2‐bis(dichlorophosphino)benzene. The new caged diphosphines are strong donor ligands and act as bridging ligand in nickel(0), rhodium(I), iridium(I) and copper(I) coordination compounds.
