It is found that while polar E X −H bonds (E 15 =group element; 16 element) feasible, analogous processes involving non‐polar 14 (CH 4 , SiH or H 2 ) proceed much higher barriers. Nevertheless, these processes, and particular dihydrogen activation, can be realizable (i. e. proceeding a feasible barrier) through rational design.

Abstract Quantum‐chemical (DFT) calculations on hitherto unknown base(carbene)‐stabilized gallium monoiodides (LB→GaI) suggest that these systems feature one lone pair of electrons and a formally vacant p‐orbital – both centered at the central atom exhibit metallomimetic behavior. The calculated reaction free energies as well bond dissociation LB→GaI are capable forming stable donor‐acceptor complexes with group 13 trichlorides. Examination ligand exchange reactions iron nickel indicates their potential use ligands in transition metal chemistry. In addition, it is found title compounds also able to activate various enthalpically robust bonds. Further, detailed mechanistic investigation small molecule activation processes reveals non‐innocent behavior carbene (base) moiety attached GaI fragment, thereby indicating cooperative nature processes. energy decomposition analysis (EDA) strain model (ASM) reactivity were employed quantitatively understand rationalize different
