Binding Small Molecules to a cis-Dicarbonyl ⁹⁹Tc^I-PNP Complex via Metal-Ligand Cooperativity.

ABSTRACT: Metal-ligand cooperativity is a powerful tool for the activation of various bonds but has rarely, if ever, been studied with the radioactive transition metal ⁹⁹Tc. In this work, we explore this bond activation pathway with the dearomatized PNP complex cis-[⁹⁹Tc^I(^PyrPNP^tBu*)(CO)₂] (4), which was synthesized by deprotonation of trans-[⁹⁹Tc^I(^PyrPNP^tBu)(CO)₂Cl] with KO^tBu. Analogous to its rhenium congener, the dearomatized compound reacts with CO₂ to form the carboxy complex cis-[⁹⁹Tc^I(^PyrPNP^tBu-COO)(CO)₂] and with H₂ to form the mo
