An easy direct arylation of 5-pyrazolones [PDF]
Beilstein Journal of Organic Chemistry, 2013 A mild, efficient and catalytic ligand-free method for the direct arylation of 5-pyrazolones by Pd-catalyzed C–H bond activation is reported. The process smoothly proceeds and yields are moderate to excellent.

Transition‐Metal‐Free Direct Arylation of Anilines
Angewandte Chemie International Edition, 2011 Aryne arylation: A new method of direct arylation is reported for aniline substrates. The reaction uses benzyne to synthesize a variety of aminobiaryls under mild conditions (see scheme), requiring no stoichiometric metalation or transition-metal catalysis.

Direct Arylation of Thiazoles [PDF]
, 2009 An introduction to the thiazole ring system is presented together with a detailed, but non-exhaustive review of the rapidly emerging area of palladium-mediated directed arylation. The direct arylation of thiazole is also discussed together with our attempts to improve the established methods.

Gold-Catalyzed Direct Arylation [PDF]
Science, 2012 Gently Coupled Linked aryl rings are found in a broad range of commercial chemical products. Currently, the most versatile synthetic route to this motif involves cross-coupling of one ring with a halide substituent to another ring with a boron or metal-based substituent. Recent research has focused on eliminating the need for one

Synthesis of Novel 3,6-Dithienyl Diketopyrrolopyrrole Dyes by Direct C-H Arylation
Molecules, 2020 Direct C-H arylation coupling is potentially a more economical and sustainable process than conventional cross-coupling. However, this method has found limited application in the synthesis of organic dyes for dye-sensitized solar cells. Although direct C-
