Abstract

ZIARANI, Ghodsi Mohammadi; BADIEI, Alireza; SHAHJAFARI, Fatemeh  and  POURJAFAR, Taiiebeh. A highly efficient solvent-free acetalization of aldehydes to 1,1-diacetates catalyzed by SiO₂-Pr-SO₃H. S.Afr.j.chem. (Online) [online]. 2012, vol.65, pp.10-13. ISSN 1996-840X.

1,1-Diacetates are prepared in excellent yields from aldehydes and acetic anhydride under solvent-free conditions at room temperature in short reaction times using catalytic amount of sulfonic acid functionalized silica (SiO₂-Pr-SO₃H) which could be easily handled and removed from the mixture of reaction.

Keywords : 1,1-Diacetates; sulfonic acid functionalized silica; acetalization; solvent-free reaction; SiO₂-Pr-SO₃H.
