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 $^{\text{99}}$Tc. In this work, we explore this bond activation pathway with the dearomatized PNP complex cis-[99TcI(PyrPNPtBu*)(CO)2] (4), which was synthesized by deprotonation of trans-[99TcI(PyrPNPtBu)(CO)2Cl] with KOtBu. Analogous to its rhenium congener, the dearomatized compound reacts with CO2 to form the carboxy complex cis-[99TcI(PyrPNPtBu–COO)(CO)2] and with H2 to form
