“…put forward a [2 + 1 + 1] cycloaddition of terminal alkyne 51 , CO and carbodiimide 53 for 5‐iminopyrrolones 54 . [ 47 ] The three‐component reaction resulted in the product in moderate to good yields (Scheme 16). The exploration of substrates revealed that the electron‐donating substituent at para ‐ position increased the yield while methyl group at the ortho position decreased.…”

Iron‐catalysed reactions are widely used in organic synthesis owing to its benefits over other metals. Among the important organic reactions, multicomponent reactions play a significant role due to its greener aspects like high atom economy, minimal amount of by‐product, economic feasibility etc. For the past few years, iron‐catalysed multicomponent reactions have attracted the attention of several chemists which lead to the invention of some fine chemistry. The majority of iron‐catalysed multicomponent reactions results in the synthesis of heterocyclic compounds having biologically active natural products, pharmaceutical etc. These developments in the iron‐catalysed multicomponent reactions are the focus of this review. This is the first review in this topic which covers the literature up to 2020, and it encompasses the different methods for the synthesis of acyclic, carbocyclic and heterocyclic compounds.

“…In 2017, Mathur and co‐workers reported a one‐pot multi‐component cycloaddition reaction of alkynes, carbodiimides, and CO for the synthesis of 5‐iminopyrrolones by using Fe(CO) 5 as the pre‐catalyst (Scheme 18). [43] As proposed in this work, Fe(CO) 5 loses one CO to form [Fe(CO) 4 ] under light irradiation, which may be the true catalytic species. Then, the subsequent coordination with one alkyne and insertion of two CO leads to the formation of a tetracarbonyl(2‐aryl/alkyl‐maleoyl) iron intermediate, which undergoes coordination with carbodiimide and releases one CO.…”

Over the past decades, organometallic complexes with precious elements, such as ruthenium and iridium, are widelyu sed as visible-light photoredox catalysts. Recently,m ore and more complexes based on earthabundant andi nexpensive elementsh ave been used as sensitizers in photochemistry.A lthough the photoexcited state lifetimes of iron complexes are typically shortert han those of traditional photosensitizers, the utilization of iron catalysts in photochemistry has sprung up owing to their abundance, low price, nontoxicity,a nd novel properties, including exhibiting ligand to metal charge transfer states. This concept focuses on recent advances in light-driven iron catalysis in organic transformations, including iron/ photoredox dual catalysis,l ight-inducedi ron photoredox catalysis and light-induced generation of active iron catalysts. The prospectf or the future of this field is also discussed.
