Palladium–N-heterocyclic carbene complexes for the Mizoroki–Heck reaction: An appraisal

One-Pot Tandem Hiyama Alkynylation/Cyclizations by Palladium(II) Acyclic Diaminocarbene (ADC) Complexes Yielding Biologically Relevant Benzofuran Scaffolds

“…With the success of the transition-metal N-heterocyclic carbene (NHC) complexes in homogeneous catalysis being well-recognized now, 1−15 their application in more challenging domains of catalysis such as bifunctional catalysis, 16,17 asymmetric catalysis, 18 and the tandem reactions 19 are of contemporary interest. Alongside, the quest for exploring new variants of the carbene ligands is being simultaneously pursued for meeting the demands of these intriguing catalyses.…”

“…Alongside, the quest for exploring new variants of the carbene ligands is being simultaneously pursued for meeting the demands of these intriguing catalyses. 1−3,5,6,20 In this context, a special class of heteroatom-stabilized singlet carbene ligands in the form of the acyclic diaminocarbene (ADC) is worth mentioning. 21−31 Owing to their remarkably simple preparative procedures, as opposed to the long and protracted preparation methods of the contemporary phosphine and the NHC ligands, the ADC ligands have attracted attention lately.…”

Imidazolium-Based N-Heterocyclic Carbenes (NHCs) and Metal-Mediated Catalysis

“…The coupling reactions catalyzed by transition metal-NHC complexes involve both C-C bond formation reactions such as Mizoroki-Heck [61,62], Sonogashira [63][64][65], Negishi [66][67][68], Hiyama [69][70][71], Suzuki-Miyaura [72][73][74], Kumada coupling [75,76], C-X (X = B, N, O) bond formation reactions such as Buchwald-Hartwig amination [77][78][79] and Ullmann coupling [80-82] etc. Recently, the coupling reactions catalyzed by the NHC-transition metal complexes have found to be efficient with commercially viable metal salts such as iron, cobalt, and nickel.…”

“…One of the best examples to demonstrate the significance of organometallic complexes is their role as catalysts in olefin metathesis, which is having numerous synthetic applications and commercial significance. There are different types of Few well-known NHC-transition metal-based catalytic applications [13,[61][62][63][64][65][66][67][68][69][70][71][72][73][74].…”

Synthesis of some new distyrylbenzene derivatives using immobilized Pd on an NHC-functionalized MIL-101(Cr) catalyst: photophysical property evaluation, DFT and TD-DFT calculations

“…43,44 In this work, in continuation of our program on the synthesis of stilbene derivatives, [45][46][47][48][49][50] a highly efficient heterogeneous catalyst system [Pd-NHC-MIL-101(Cr)] 51 was introduced to be applied in the synthesis of stilbene derivatives using Mizoroki-Heck coupling reaction. [52][53][54][55][56][57] The Pd-NHC-MIL-101(Cr) catalyst system showed remarkable catalytic activity in the Heck reaction 51 and in order to further show its utility in organic synthesis we investigate its applicability in the synthesis of distyrylbenzenes (DSBs). The synthetic pathway toward synthesis of [Pd-NHC-MIL-101(Cr)] catalyst system is shown in Scheme 1.…”
