A C-H borylation approach to suzuki-miyaura coupling of typically unstable 2-heteroaryl and polyfluorophenyl boronates

A method for the synthesis of biaryls and heterobiaryls from arenes and haloarenes without the intermediacy of unstable boronic acids is described. Pinacol boronate esters that are analogous to unstable boronic acids are formed in high yield by iridium-catalyzed C-H borylation of heteroarenes and fluoroarenes. These boronates are stable in the solid state or in solution and can be generated and used in situ. They couple with aryl halides in the presence of simple palladium catalysts, providing a convenient route to biaryl and heteroaryl products that have been challenging to prepare via boronic acids.

Aversatile palladium/triphosphane system for direct arylation of heteroarenes with chloroarenes at low catalyst loading

Put a ring on it: The use of an air-stable, robust palladium/tridentate phosphane catalyst in direct C-H and C-Cl activation reactions is reported (see scheme; DMAc=N,N-dimethylacetamide, TBAB=tetra-n-butylammonium bromide). Electron-rich, electron-poor, and polysubstituted furans (X=O), thiophenes (X=S), pyrroles (X=NR5), and thiazoles were arylated with chloroarenes in the presence of the catalyst.

Low catalyst loading ligand-free palladium-catalyzed direct arylation of furans: An economically and environmentally attractive access to 5-arylfurans

The direct 5-arylation of furans at very low catalyst loading using Pd(OAc)2 as catalyst without added ligand proceed in high yields. Turnover numbers up to 10000 have been obtained for the coupling of several activated aryl bromides. A wide ra
