摘要

Stoichiometric reducing agents have been important tools for studying and understanding electronic structure and bonding in myriad chemical systems. Dennis L. Lichtenberger, Carlos A. Murillo, and colleagues report the general synthesis and photoelectron spectra of two new compounds with tungsten-tungsten quadruple bonds that add to the family of strong reducing agents for such work (DOI: 10.1021/ja408291k). These compounds are thermally stable and easy to synthesize in high yields and good purity. Modification of the bicyclic guanidinate ligands significantly increases the solubility of the compounds in nonpolar solvents, thereby increasing the number of potential chemical systems in which the ditungsten compounds could be applied.
