A one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using chloroarenes and palladium catalysts is disclosed. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores.

of free benzoicacids have been developed. The first method employs stoichiometric silver acetate for iodide removal, aryl iodide as the coupling partner, and acetic acid solvent. This method is applicable to the arylation of electron-rich to moderately electron-poor benzoicacids and tolerates chloride and bromide substituents on both coupling partners. The second method involves the use of aryl chloride
