Resumen

SHELKE, Kiran et al. An efficient and green procedure for the preparation of acylals from aldehydes catalyzed by alum [KAl(SO4)2-12H2O]. S.Afr.j.chem. (Online) [online]. 2009, vol.62, pp. 109-112. ISSN 1996-840X.

Alum [KAl(SO4)2-12H2O] is an inexpensive, efficient, non-toxic and mild catalyst for the preparation of acylals from aromatic and heteroaryl aldehydes with acetic anhydride at room temperature under solvent-free conditions. This method gives remarkable advantages such as excellent chemoselectivity, mild reaction conditions, short reaction times and excellent yields, and offers a green synthetic solution by avoiding toxic catalysts and hazardous solvents.

Palabras clave : Alum; acylals; aromatic and heteroaryl aldehydes; solvent-free synthesis; room temperature.
