The position and number of substituents in pyridine ligands (X nPy) were correlated with structural, physical, and chemical properties of PdCl2(XnPy)2 complexes applied as catalysts for the carbonylation of aromatic nitrocompounds (phosgene-free method of carbamates production). Thermal stability and catalytic activity of PdCl2(XnPy)2 complexes without steric hindrance increases with increasing XnPy’s basicity whereas a decrease of thermal stability and catalytic activity of the complexes is observed for sterically crowded complexes (with the ortho-substituted XnPy). The complexes with X = Cl in meta- position of XnPy decompose to a mixture of PdCl2 and metallic Pd (similarly to complexes with Me nPy) whereas complexes with ortho-chlorine (in XnPy) decompose to the organopalladium products. Therefore, two different mechanisms of thermal decomposition are proposed for PdCl2(Cl nPy)2 and PdCl2(MenPy)2. The results of complex thermal and structural analysis of a series of PdCl 2(XnPy)2 complexes allow us to get insight into the mechanism of nitrobenzene (NB) carbonylation catalyzed by PdCl 2(XnPy)2 at 150-180 C. We conclude that the electron transfer from Pd(0) to nitrobenzene is the rate determining step of catalytic cycle of NB carbonylation.

The overall rate constants for the reaction of OH with pyridine, its three monosubstituted methyl derivative isomers (the picolines), its six disubstituted methyl derivative isomers (the lutidines), and its three monosubstituted ethyl derivative isomers have been measured using the turbulent flow technique with high-pressure chemical ionization mass spectrometry at 100 Torr pressure and 298 K. A structure-reactivity relationship model for parametrizing the OH rate constants based on the type and position of the methyl and ethyl substituents on the pyridine ring has been constructed, and similar accuracy to that previously obtained for benzene derivative rate data is achieved. Transition state theory calculations have been performed to explore the substituent effect on the observed OH rate constants. The atmospheric implications of the findings are discussed in terms of the role of pyridinated compounds in the ionic composition of the troposphere.

Me groups on nitrogenous heterocycles can be conveniently metallated by a variety of strongly basic reagents to afford synthetically useful carbanions.The negative charge of such anions resides predominantly on the ring N atoms.The site of lithiation on pyridines and quinolines bearing Me groups in both the 2- and 4-positions depends upon the ability of the ring N atom to complex with the metallating agents.Carbanions derived from methylated pyridines, quinolines, naphthyridines, isoquinolines, pyrido<4,3-b>carbazoles, pteridines, pyrido<3,4-b>indoles and quinoxalines are discussed.References are provided describing condensations of these reagents with a variety of both common and uncommon electrophiles.

Superoxide is involved in the pathogenesis of various diseases, such as inflammation, ischemia-reperfusion injury and carcinogenesis. Superoxide dismutases (SODs) catalyze the disproportionation reaction of superoxide to produce oxygen and hydrogen peroxide, and can protect living cells against the toxicity of free radicals derived from oxygen. Thus, SODs and their functional mimics have potential value as pharmaceuticals. We have previously reported that Fe(II)tetrakis-N,N,N’,N’-(2-pyridylmethyl)ethylenediamine (Fe(II)TPEN) has an excellent SOD activity (IC50=0.5 muM) among many iron complexes examined (J. Biol. Chem., 264, 9243-9249 (1989)). Fe(II)TPEN can act like native SOD in living cells, and protect Escherichia coli cells from free radical toxicity caused by paraquat. In order to develop more effective SOD functional mimics, we synthesized Fe(II)TPEN derivatives with electron-donating or electron-withdrawing groups at the 4-position of all pyridines of TPEN, and measured the SOD activities and the redox potentials of these complexes. Fe(II) tetrakis-N,N,N’,N’-(4-methoxy-2-pyridylmethyl)ethylenediamine (Fe(II)(4MeO)4TPEN) had the highest SOD activity (IC50=0.1 muM) among these iron-based SOD mimics. In addition, a good correlation was found between the redox potential and the SOD activity of 15 Fe(II) complexes, including iron-based SOD mimics reported in the previous paper (J. Organometal. Chem., in press). Iron-based SOD mimics may be clinically applicable, because these complexes are generally tissue-permeable and show low toxicity. Therefore our findings should be significant for the development of clinically useful SOD mimics.
