“…Along with iron salts, magnetic catalysts were also widely used in the fields of catalysis. [ 26–31 ] Also, the catalytic activity of iron in multicomponent reactions was explored well for the synthesis of diversely functionalized organic moieties. Even though the area has developed a lot, a comprehensive review on iron‐catalysed MCRs is lacking.…”

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.

“…A cross coupling reaction is a reaction where two fragments are fused together with the support of metal catalyst. Suzuki–Miyaura coupling, [ 20–22 ] Heck reaction, [ 23,24 ] Stille coupling, [ 25 ] and Sonogashira coupling [ 26,27 ] are some of the most versatile and successful synthetic tools for carbon–carbon bond formation. Synthetic methodologies for chalcones have some drawbacks like requirement of strong basic or acidic reaction conditions, low yield of products, harsh reaction conditions, long reaction time, usage of toxic reagents, and low selectivity.…”

For the last two decades, chalcones and their derivatives have attracted special interest among researchers due to their pharmaceutical properties. Numerous research works have been still going on to improve the methodologies of chalcone synthesis. Chalcone has displayed a remarkable curative efficiency to cure numerous diseases and it continues to show promise for new drug investigations. This review highlights the metal catalysed cross‐coupling reactions for the synthesis of chalcone and its derivatives from 2009 to 2020.

“…More than 90% of the current commercial chemical and pharmaceutical products are believed to be produced through catalytic transformations, and most of the efficient catalysts used comprise of the noble transition metals, which are expensive and toxic. 1 Palladium catalysts have been extensively applied in homogeneous catalysis for their high efficiency and selectivity, 1,2 but heterogeneous palladium catalysts have many advantages over the homogeneous counterparts such as the ease for separation, recovery and reuse of the toxic and expensive palladium catalyst, [3][4][5] thus they are clearly greener and more sustainable alternatives. In addition, heterogenization of palladium catalysts will also minimize waste generation and transition metal contamination in the final products, hence, it has attractive economic and sustainable environmental (green chemistry) benefits for development of more environmentally benign procedures in a wide range of chemical and industrial processes.…”

A simple and green chemical modification coupled with electrospinning technique has been developed to incorporate tetrakis(triphenylphosphine)palladium [Pd(PPh3)4] inside crosslinked polystyrene nanofibers (Pd@CPS) as an efficient and stable heterogeneous palladium catalyst. The catalytic activities and recyclabilities of the prepared Pd@CPS catalyst have been evaluated by using Suzuki and Heck reactions of various aromatic halides separately with phenylboronic acid and alkenes. The Pd@CPS exhibited high‐catalytic activities for the Suzuki and Heck reactions of aromatic iodides to afford the products in excellent yields (coupling yields >88%). The catalytic activities and the nanofiber structure remained essentially unchanged even after recycling for five times. The high activities and stabilities of the prepared Pd@CPS catalyst can be attributed to the ultrafine fiber and embedment of palladium active species inside the nanofibers.
