“…On the other hand, considerable attention has also been given to copper catalysis in the field of cross-coupling reactions during the last decade, owing the low cost of the catalysts, good functional group tolerance, high abundance, and low toxicity. [19][20][21][22][23][24][25] Besides which, copper plays a crucial role in cross-coupling reactions, and its scope and practicality in the bond formation processes of C-N, C-O, C-P, and C-C bonds has substantially grown. Most well-known catalytic processes use a single catalyst to achieve the de-…”

Coupling reactions stand amid the most significant reactions in synthetic organic chemistry. Of late, these coupling strategies are being viewed as a versatile synthetic tool for a wide range of organic transformations in many sectors of chemistry, ranging from indispensable synthetic scaffolds and natural products of biological significance to novel organic materials. Further, the usage of dual-catalysis in accomplishing various interesting cross-coupling transformations is an emerging field in synthetic organic chemistry, owing to their high catalytic performance rather than the usage of a single catalyst. In recent years, synthetic organic chemists have given considerable attention to hetero-dual catalysis, wherein these catalytic systems have been employed for the construction of versatile carbon-carbon [C(sp3)–C(sp3), C(sp3)–C(sp2), C(sp2)–C(sp2), etc.] and carbon-heteroatom (C-N, C-O, C-P, C-S, etc.) bonds. Therefore, in this mini-review, we are emphasizing recently developed various cross-coupling reactions catalysed by transition-metal dual-catalysis (i.e., using palladium and copper catalysts, and by omitting the reports on photoredox/metal catalysis).

“…Some reviews summarized recent advances in copper-catalyzed C H functionalization. [62,63] For over a century, copper-mediated reactions have played an important role in organic chemistry, as evidenced by numerous important transformations and name reactions. Indeed, Ullmann-type reactions can be thought of as forerunners of modern cross-couplings.…”

Due to their outstanding physicochemical features, azulene derivatives have been proposed for a wide range of prospective technical applications, including molecular switching, sensors, solar cells, and beneficial biological activities. Transition metal‐catalyzed cross‐coupling reactions are catalytic processes that create carbon–carbon bonds in one of the most straightforward and practical ways possible. These techniques have proven to be a very practical way to functionalize azulene. This study summarizes the progress made in this field by employing Rh, Ir, Ru, Au, Fe, Ni, and Cu catalysts over the last two decades.

“…Subsequently, this protocol was extrapolated by several groups using other metals or metal-free conditions via the single electron activation of aryl carboxylic acids ( Scheme 1 A). ( Bhunia et al., 2019 ; Dai et al., 2015 ; Li et al., 2013 , 2018 ; Ramirez et al., 2015 ; Shao et al., 2018 ; Tao et al., 2018 ; Wang et al., 2014 ; Yang et al., 2018 ; Zhang et al., 2018a , 2018b ) Although soluble copper complexes or copper nanoparticles (CuNPs) have been used for the C‒H functionalization ( Aneeja et al., 2020 ; Guo et al., 2015b ), the use of inexpensive bulk Cu catalyst is extremely rare ( Guo et al., 2015a ; Meng et al., 2020 ). Recent efforts to bridge the gap between hetero- and homogeneous catalysis for improved catalytic activity, selectivity, and cost efficiency is prevailing ( Copéret et al., 2003 ; Cui et al., 2018 ; Liu and Corma, 2018 ; Van Velthoven et al., 2020 ).…”
