Overview
abstract
The new family of rigid PNP pincer ligands supports a wealth of exciting transition metal chemistry. The usefulness of the PNP ligands extends to both borders of the transition-metal series. Such versatility exists because of the rigid backbone that prearranges three donor atoms for binding a transition metal and also because of the hybrid nature of PNP, incorporating both hard amido donors and soft phosphine donors. In the early metals, the chemistry of group-4 metal-carbon multiple bonds significantly extend beyond the previously known precepts. In the late metals, particularly those of groups 9 and 10, the PNP ligands serve as robust ancillary ligands in diverse catalytic processes. In addition, the new PNP ligands are used to engender unusual organometallic reactions and to support new structural motifs. 2007 Elsevier B.V. All rights reserved.
