Abstract
α,β-Unsaturated carbonyl compounds are versatile building blocks in modern organic
synthetic chemistry. In recent decades, various approaches have been established to
access to these products, such as halogenation–dehydrohalogenation methods, organosulfur
methods, organoselenium methods, earth-abundant-metal-catalyzed methods, precious-metal-catalyzed
methods, and metal-free methods, etc. Among these, earth-abundant-metal-catalyzed
methods (i.e., iron, cobalt, nickel, copper) continue to attract the attention of
chemists because they are readily available, inexpensive, and environmentally friendly.
Presently, there are only a few reviews covering earth-abundant-metal-catalyzed α,β-dehydrogenations.
Hence, the aim of this short review is to provide a detailed update on the recent
developments on earth-abundant-metal-catalyzed α,β-dehydrogenations of carbonyl compounds.
