ATE complex

ATE complex

An "ate complex" is a type of chemical compound that is formed when a metal or non-metal atom is bonded to a negatively charged ligand, typically ending in "-ate". These complexes are often named after the ligand they are bonded to and are commonly used in chemical reactions and catalysis.From: A Q&A Approach to Organic Chemistry [2020], An efficient base and H₂O₂ free protocol for the synthesis of phenols in water and oxygen using spinel CuFe₂O₄ magnetic nanoparticles [2020]

An “ate” complex is the product of a Lewis acid–Lewis base reaction, which is the Lewis acid–Lewis base adduct. What is the product when the Lewis acid AlCl3 reacts with ammonia (NH3)?

Initially, the boron atom adopts sp2 hybridization in organoboronic acids [47] and gets activated by coordinating on the surface of the CuFe2O4 as Lewis acidic sites. The boron group thus changes from being a low reactive electrophile into a moderately reactive electrophile due to its coordination to the acidic sites on the surface of the catalyst. The addition of O2+H2O generates a tetravalent boron “ate” complex and induces rehybridization to form sp3 boron in the –O2H oxidative pathway. Due to the high electron density on boron and increased steric crowding in the “ate” complex the C-B bond dissociates and subsequent aryl migration to the adjacent acceptor oxygen with retention of configuration takes place with elimination of H2O. This H2O molecule than approaches the intermediate (a) and hydrolysis step occurs to form the final phenol product.
