(N-Heterocyclic Carbene)PdCl₂(TEA) Complexes: Studies on the Effect of the “Throw-Away” Ligand in Catalytic Activity

Suzuki–Miyaura and Hiyama coupling catalyzed by PEPPSI-type complexes with non-bulky NHC ligand

“…There are many examples of the application of PEPPSI complexes in the Suzuki-Miyaura reaction, in which their excellent catalytic activity and versatility are clearly evidenced [18][19][20][21][22][23][24]. In contrast, their applications in the Hiyama coupling are rather scarce [25][26][27].…”

Bis(imino)acenaphthene (BIAN)-supported palladium(ii) carbene complexes as effective C–C coupling catalysts and solvent effects in organic and aqueous media

“…5 Complexes based on group X metals are the most proficient in this task and can be rendered soluble in appropriate organic solvents using a range of spectator ligands such as 3-chloropyridine, triethylamine, and allyl moieties. [6][7][8][9] Suzuki catalysts often employ bulky phosphine ligands that result in optimal catalytic activity and selectivity. However, phosphine ligands are typically susceptible to oxidation and metal-ligand degradation.…”

Structure–activity relationship of N‐heterocyclic carbene–Pd(II)–imidazole complexes in Suzuki–Miyaura coupling between 4‐methoxyphenyl chloride and phenylboronic acid

“…In addition, compared to analogous structures with 3-chloropyridine, [1f,4] triethylamine, [5] diethylamine [6] and other N-donors involving structures as the 'throw-away' ligands, [7] complex 1a showed similar catalytic activity. To understand the effect of imidazole and NHCs, we synthesized a number of NHC-Pd(II)-Im complexes, and their catalytic activities in the Suzuki-Miyaura coupling between 4-methoxyphenyl chloride 2 and phenylboronic acid 3 were investigated.…”
