摘要：

The impact of varied chalcogen bonds (sulfur, selenium, tellurium, and telluronium) on dynamic imine chemistry in aqueous solution is presented by introducing a carboxylate group or cationic telluronium into arylaldehydes. The role of chalcogen bonding in regulating the kinetics and thermodynamics of imine formation/exchange was elucidated through experimental and computational evidence, affording the largest effect for tellurium/telluronium compounds. By leveraging multivalent chalcogen bonding, telluronium-containing aldehyde enabled labeling of the N-terminus of amino acids in neutral buffer.
