Efficient Sonogashira Coupling Reaction Catalyzed by Copper (I) Iodide in the Presence of KF/Al2O3 [PDF]
شیمی کاربردی روز, 2009 We have developed a convenient and efficient method for coupling of aryl iodides and bromides with terminal alkynes. The protocol uses CuI as catalyst, 1, 10-phenanthroline as ligand, KF/Al2O3 as base and toluene as solvent.

Reactions coupled to palladium [PDF]
Nature Chemistry, 2012 You would be forgiven if you thought the most important element in an organic transformation was carbon. Matthew Hartings argues that, for just over half a century in many of chemistry's most renowned organic reactions, it has actually been palladium.

Cross-coupling Reactions of Monosubstituted Tetrazines [PDF]
Organic Letters, 2021 A Ag-mediated Pd-catalyzed cross-coupling method for 3-bromo-1,2,4,5-tetrazine with boronic acids is presented. Electronic modification of the 1,1′-bis(diphenylphosphine)ferrocene (dppf) ligand was found to be crucial for good turnover. Using this fast method, a variety of alkyl-, heteroatom-, and halide-substituted aryl- and heteroaryl-tetrazines were

Gold-Catalyzed C(sp3)-C(sp2) Suzuki-Miyaura Coupling Reaction
, 2023 A gold-catalyzed C(sp3)-C(sp2) Suzuki-Miyaura coupling reaction facilitated by the ligand-enabled Au(I)/Au(III) redox catalysis was developed. The cross-coupling of alkyl organometallics was first realized in the redox catalytic cycle in gold chemistry ...
