A convenient procedure for the preparation of 1-(diisopropylamino)phospholes - Application to the synthesis of new 2,2′-biphosphole disulfides

A convenient one-pot procedure for the preparation of 1-(diisopropylamino)phospholes has been developed. These phospholes have been used in a multistep procedure for synthesizing two new 2,2′-biphosphole disulfide compounds. The structures and stereochemistry of these compounds have been studied by X-ray diffraction analysis and by molecular modeling. The 1-(diisopropylamino) group, used as a bulky substituent on the phosphorus atom in combination with a phenyl group on the ring, proved to be an important factor in the stabilization of the axial chirality of 2,2′-biphosphole framework.
