Iron(III) Trifluoroacetate: Chemoselective and Recyclable Lewis Acid Catalyst for Diacetylation of Aldehydes, Thioacetalization and Transthioacetalization of Carbonyl Compounds and Aerobic Coupling of Thiols

摘要

Iron(III) trifluoroacetate [Fe(CF3CO2)3] was found to be a recyclable, highly efficient and chemoselective Lewis acid catalyst for protection of a variety of carbonyl compounds as thioacetals under nearly neutral conditions.
