Abstract

Catalysis

Esterification

Oxazadisilinane

Siloxane protic ionic liquids

[Display omitted] •A new family of 21 siloxane protic ionic liquids (Si-PILs) were synthesized and characterized.•Analysis of crystal structures reveals intermolecular hydrogen bonding interactions.•Recyclability of Si-PILs in catalyzing esterification of acetic acid and alcohols was demonstrated. A series of oxazadisilinane compounds were prepared and used as Brønsted bases to form a series of 21 siloxane protic ionic liquids (Si-PILs) with four different acids. This new family of Si-PILs were well characterized and examined to catalyze esterification reactions.
