Erbium(iii) chloride is a powerful catalyst for the acylation of alcohols and phenols. The reaction works well for a large variety of simple and functionalized substrates by using different kinds of acidic anhydrides (Ac 2O, (EtCO)2O, (PriCO)2O, (Bu tCO)2O, and (CF3CO)2), without isomerization of chiral centres. Moreover, the catalyst can be easily recycled and reused without significant loss of activity. CSIRO 2007.

formula presented The acylphosphoranes formed in a sequential manner from the reaction of the silyl ester of O-acyl(aroyl)salicylic acids and (trimethylsilyl)-methylenetriphenylphosphorane undergo intramolecular Wittig cyclization on the ester carbonyl to afford the 4H-chromen-4-ones in good to excellent yields.

The transport of aspirin (ASP) and its derivatives (m- or p-acetoxybenzoic acid (m- or p-AcOHBA), o-propionyloxybenzoic acid (PrOHBA), o-butyryloxybenzoic acid (BuOHBA), o-acetoxyhippuric acid (AcOHPA), and o-acetoxy-N-benzoyl-β-alanine (AcONBA)) through
Acylcobalt salophen complexes. Homolytic decomposition to salicyl aldehyde esters
Pattenden, Gerald,Tankard, Mark
, p. 237 - 240 (2007/10/02)
Irradiation of acylcobalt salophen complexes leads to salicyl aldehyde ester products resulting from cobalt-to-oxygen migration.
