An easily synthesized tetraphosphine N,N,N′,N′-tetra(diphenylphosphinomethyl)-pyridine-2,6-diamine (TPPDA) in combination with PdCl2 was proved to be a highly efficient catalyst for Suzuki-Miyaura cross-coupling. This system could catalyze a variety of aryl halide substrates with a wide range of functional groups as well as heteroaryl halides. A high turnover number (TON) up to 3,350,000 was reached for 3-bromochlorobenzene.

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.

Na2S2O8-promoted decarboxylative cyclization of biaryl-2-oxamic acid for phenanthridinones has been developed. This work illustrates the first example of intramolecular decarboxylative amidation of unactivated arene under transition-metal-free conditions. Additionally, this approach provides an efficient and economical method to access biologically interesting phenanthridinones, an important structure motif in many natural products.

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.

Triphenylphosphine-mediated reductive cyclization of 2-nitrobiphenyls: A practical and convenient synthesis of carbazoles
Freeman, Adam W.,Urvoy, Marie,Criswell, Megan E.
, p. 5014 - 5019 (2007/10/03)
The synthesis of a series of substituted carbazoles from the corresponding 2-nitrobiphenyl derivatives using a novel modification of the Cadogan reaction is described. Cyclization of the 2-nitrobiphenyls was achieved via reductive deoxygenation of the nitro groups using a slight excess of triphenylphosphine in a suitable solvent. We have observed a temperature dependence on the extent of conversion under these conditions, with higher boiling solvents affording higher yields across a range of substrates. The new reaction conditions are very straightforward and convenient to execute, tolerate a broad range of functional groups, and yield carbazole products in the absence of unwanted side products.

Cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclo pentane/[PdCl(C3H5)]2 system catalyses the cross-coupling of aryl chlorides with arylboronic acids with high ratios substrate/catalyst. A turnover number of 6800000 has been obtained for the addition of the activated 2-chloro-5-(trifluoromethyl)nitrobenzene to benzeneboronic acid in the presence of this catalyst.
