Intracrystalline reactivity of layered double hydroxides: carboxylate alkylations in dry media
Abstract
This work concerns the reactivity in dry media conditions, i.e. without solvents, of layered double hydroxide (LDH) solids, containing carboxylate ions in their structure, towards alkyl and benzyl halides. Reaction occurs giving the corresponding esters, with excellent yield and selectivity, and preserving the lamellar arrangement of the pristine solids. The reactions were activated by conventional thermal treatment (100 °C) or by microwave (MW) irradiation.
