Interactional Features of (RO) <sub>4</sub> Ti Species and Their Zr and Hf Analogues
Abstract Tetroxides of Group 4 elements are benchmark catalysts for aldol reactions and oxidation processes, achieving high yields and regio‐, diastereo‐, and enantioselectivities. Our computational analyses and experimental studies, performed in solution and solid, consistently reveal that these tetroxides form attractive interactions with lone pair compounds exhibiting distinctive σ‐hole bond features. We propose naming these novel bondings as titan bonds (TnBs). These new insights into Ti/Zr/Hf tetroxide interactions may significantly aid in designing more effective catalysts with enhanced selectivities.
