A long-standing challenge in Minisci reactions is achieving the arylation of heteroarenes by oxidative decarboxylation of aromatic carboxylic acids. To address this challenge, the silver-catalyzed intermolecular Minisci reaction of aromatic carboxylic acids was developed. With an inexpensive silver salt as a catalyst, this new reaction enables a variety of aromatic carboxylic acids to undergo decarboxylative coupling with electron-deficient arenes or heteroarenes regardless of the position of the substituents on the aromatic carboxylic acid, thus eliminating the need for ortho-substituted aromatic carboxylic acids, which were a limitation of previously reported methods.

An air-stable tetraphosphine N,N,N′,N′- tetra(diphenylphosphinomethyl)-benzene-1,3-diamine (L3) was easily prepared in two steps from triphenylphosphine, which in combination with [Pd(η3-C3H5)Cl]2 affords an efficient catalyst for Suzuki-Miyaura coupling of activated chloroarenes. Even at high temperature of 130 C, this catalyst exhibits good stability and longevity, and could allow a high turnover number of 680,000 to be reached.
