This content is a preprint and has not undergone peer review at the time of posting.


A new monoanionic pentadentate ligand is designed to accommodate Sc=E bonds (E = N, P). The imido complex is stable enough to isolate and characterize, and reacts rapidly with CO2. The phosphinidene, on the other hand, is highly reactive and induces C-C bond cleavage to yield a phosphido-pyridyl complex which also undergoes rapid reacton with CO2.
