An isolable donor-stabilized silavinylidene phosphorane was synthesized. This molecule, which can also be regarded as a new carbon(0) complex featuring a phosphine and a donor-stabilized silylene ligand, presents a central carbon atom with a remarkably high electron density (−1.82). Furthermore, the experimental electron-density study of this compound demonstrates the delocalization of the σ-lone pair at the central carbon atom toward the silicon center, a feature which is remarkably different from electronic situation of other bent-allene-type molecules. This result clearly demonstrates the powerful electron-donating ability of donor-stabilized silylene ligands, as well as their excellent electron-acceptor properties. Generous donors: Donor-stabilized silavinylidene phosphoranes were synthesized and isolated as stable molecules. These new carbon(0) complexes, featuring a phosphine and donor-stabilized silylene (DSS) ligand, present a central carbon atom with a remarkably high electron density (−1.82). This result clearly demonstrates the powerful electron-donating ability of DSS ligands toward atomic carbon.
