Title Direct oxidative esterification of benzaldehydes and benzylalcohols using task-specific imidazolium based perchlorate ionic liquid Type of Research Article Keywords Direct oxidative esterification, Esterification of benzaldehydes, Esterification of benzylalcohols, Perchlorate ionic liquid, Task-specific ionic liquid Abstract Imidazolium perchlorate task-specific ionic liquids (TSILs) were used for in-situ oxidation esterification of benzaldehydes and benzylalcohols in reaction with alcohols. CO2H functional group containing TSIL show dual role as catalyst and reaction media toward oxidative esterifications. Excellent yields of esters could be obtained for a series of benzaldehydes and benzylalcohols via the reaction with alcohols. This reaction can be regarded as a new method for the efficient oxidation esterification of benzaldehydes and benzylalcohols under mild catalyst and solvent-free conditions.
