Palladium-catalyzed arylation of simple arenes with iodonium salts
The development of an arylation protocol for simple arenes with diaryliodonium salts using the Herrmann-Beller palladacycle catalyst is reported. The reaction takes simple aromatic feedstocks and creates valuable biaryls for use in all sectors of the chem

Ligands for metals and improved metal-catalyzed processes based thereon
One aspect of the present invention relates to ligands for transition metals. A second aspect of the present invention relates to the use of catalysts comprising these ligands in transition metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The subject methods provide improvements in many features of the transition metal-catalyzed reactions, including the range of suitable substrates, reaction conditions, and efficiency.

Aromatic hydrocarbons in the gaseous and condensed phase. A nuclear decay study
A nuclear technique based on the spontaneous decay of tritiated precursors has been used in a comparative stydy of aromatic phenylation by free phenylinium ions, both in the gas and liquid phase.The mechanism of the major competitive processes promoted by phenylinium ion attack, are discussed.
Photolysis of Some ortho-Methylated Monochlorobiphenyls
A series of monochloro-o-methylated biphenyls was photolysed.Quantum yields of dechlorination lie in between the low values observed for 3- and 4-chlorobiphenyl and the high values obtained for 2-chlorobiphenyl.The results are interpreted in terms of raising the energy of the excited state due to steric crowding of the ortho-substituent and relief of strain upon the departure of an ortho-chlorine.
