The palladium complex [Pd(L)Cl2] (1) has been prepared by the reaction of Pd(COD)Cl2 (COD = 1,5-cyclooctadiene) with L [N,N′-bis(diphenylphosphanyl)-2-(diphenylphosphanyl)ethanamine]. The ligand L and complex 1 have been characterized by elemental analysis, mass spectrometry and 1H/31P NMR spectroscopy. In the presence of O2, 1 selectively catalyzes the hydroxylation of a variety of arylboronic acids to the corresponding phenol derivatives in solvents with low-dielectric constants at 298 K, although in solvents with high dielectric constants the same reaction leads to the formation of both phenol and the coupled product, i.e. biaryl. The mechanistic aspects of the selective phenol formation from arylboronic acid with 1 have been addressed.
Physical, spectral and chromatographic properties of all 209 individual PCB congeners

Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations. -from Authors
