VSO₄.5H₂O: A Mild and Efficient Catalyst for Chemo‐Selective Conversion of Aldehydes to 1,1‐Diacetates

Abstract

Protection of aliphatic and aromatic aldehydes as 1,1‐diacetates using VSO4.5H2O under solvent‐free conditions is carried out. The products are obtained in good to excellent yields. Ketones are not affected under these conditions.

Hydrated ferric perchlorate, Fe(ClO4)3.XH2O in organic synthesis. A short review

“…The synthesis of this eminent family of compounds has been previously reviewed [122]. These compounds were synthesized in mild conditions starting from 1,3-diketones and phenyl hydrazine in the presence ferric perchlorate hexahydrate and supported ferric perchlorate hexahydrate on silica gel as catalyst (Scheme 20) [123].…”
