Synthesis, Characterization, and Reactivity of a d, Mo(IV) Complex Supported by a New OCO-Trianionic Pincer Ligand

摘要

Early (groups 3-6) and late (groups 7-10) transition metal complexes have distinct structural and reactivity properties. Early metals favor high oxidation states, high coordination numbers, are typically electrophilic and are intolerant of many functional groups. The opposite is true for late metal complexes, in which low coordinate and low oxidation states prevail and a wide range of functional groups are tolerated.1 By altering the properties of ancillary ligands, chemists are able to manipulate the inherent properties of a specific metal to promote and amplify reactions.
