Copper-catalyzed selective oxygenation of methyl and benzyl substituents in pyridine with O2

A selective oxygenation of picolines and their derivatives has been achieved by usingasimple copper salt as a catalyst and molecular oxygen as an oxidant, where the alpha-position of the alkyl substituent is selectively oxidized to give the corresponding aldehydes or ketones. Addition of a catalytic amount of water enhances the catalytic activity, which could be attributed to the role of the proton donor to activate the substrates.

Kinetics and Mechanism of Halogen-bridge Cleavage in Dimethylaminomethylphenyl-C1,N Pallada- and Platina-cycles by Pyridines. Pressure Effects, and Crystal Structures of the N,N-cis Reaction Product, its N,N-trans Orthometallated Analogue and a Dimer of Similar Reactivity

An ambient and high-pressure stopped-flow kinetic study of the halogen-bridge cleavage reaction in the pallada- and platina-cycles <2> (M = Pd or Pt; R = H, 4-MeO, 5-Me or 5-F; X = Cl or I) by a series of substituted pyridines in chloroform as solvent revealed that it is a fast, associatively driven second-order process, with strong steric rather than electronic demands.Substituent effects and activation parameters (DeltaH(excit.),DeltaS(excit.) and DeltaV(excit.)) were in full accord with the proposed associative mechanism.The Pd dimers transformed into N,N-trans monomers of the type (py = pyridine).In contrast, the Pt counterparts afford N,N-cis species under the same conditions.The geometry of the N,N-cis complex X(py)>, as well as of the N,N-trans platinacycle Cl(py)>, has been confirmed by X-ray crystallography.The most striking structural differences in the N,N-cis and N,N-trans related platinacycles are the Pt-Cl and Pt-N(py) bond distances <2.300(1) and 2.408(5), 2.138(4) and 2.02(1) Angstroem, respectively>.The crystal structure of trans-<(n-Bu3P)IPd(mu-I)2PdI(P-n-Bu3)> has also been determined and used to account for its similar reactivity to <2> in the bridge-splitting reaction.

Synthesis and electrochemical properties of mono- And (¡À)-l,2-dia!kylferrocenes and alkylferrocenium hexafluorophosphates in aqueous and micellar media

Simple methods have been developed for the preparation of a series of n-alkylferrocenes H(CH2)Fc (n = 3, 5-8, or 12) based on Friedel-Crafts acylation of ferrocenes followed by reduction of the corresponding ketones with Zn amalgam. The properties of H(CH2>nFc and the corresponding ferrocenium ions in micellar aqueous solutions and the behavior of watersoluble cations H(CH2)nFc+ in the absence of micelles were studied by cyclic voltammetry. In all cases, the formal redox potentials of ferrocenes (? ‘) increase linearly as n increases up to 8. Whether micelles are present or not, the corresponding correlation equation has the following form: ?”‘= a + pn, where beta= 29 mV in all cases. The synthesis of (¡À)-l-ethyI-2methylferrocene from racemic a-dimethylaminoethylferrocene is reported.

Structure-activity study of pyridine derivatives inhibiting thromboxane synthetase

The relationship between the structure of the side chain of pyridine derivatives and the inhibitory potency towards thromboxane synthetase was quantitatively analyzed by the adaptive least-squares (ALS) method. The main descriptors concerning the molecular structure used in the analysis were estimated on the basis of the minimum energy conformation obtained from MINDO/3 molecular orbital calculation. All of 27 pyridine derivatives were recognized correctly by the best discriminant function. Validity of the discriminant function was tested by the leave-one-out technique. The activity ratings of 23 compounds could be predicted correctly with the descriptors used in the best function. Application of this relationship to the design of inhibitors and the mode of enzyme-inhibitor interaction were discussed.

Vapor pressures, high-temperature heat capacities, critical properties, derived thermodynamic functions, and barriers to methyl-group rotation, for the six dimethylpyridines

Measurements leading to the calculation of ideal-gas thermodynamic properties at p = p0 = 101.325 kPa are reported for the six dimethylpyridines (Chemical Abstract registry numbers: 2,3-dimethylpyridine <583-61-9>; 2,4-dimethylpyridine <108-47-4>; 2,5-dimethylpyridine <589-93-5>; 2,6-dimethylpyridine <108-48-5>; 3,4-dimethylpyridine <583-58-4>; and 3,5-dimethylpyridine <591-22-0>).Vapor pressures were measured for each compound by comparative ebulliometry for the pressure range 2 kPa to 270 kPa.Two-phase (liquid + vapor) heat capacities were measured with a differential scanning calorimeter (d.s.c.), and saturation heat capacities Csat,m were derived.Densities for the liquid phase of 2,3-dimethylpyridine and 2,6-dimethylpyridine were measured with a vibrating-tube densitometer.The critical temperature Tc was determined experimentally for each compound by d.s.c., and the critical pressure and critical density were derived from fitting procedures.Enthalpies of vaporization were calculated from the experimental measurements.Entropies and enthalpy increments by adiabatic heat-capacity calorimetry, published recently by this research group, and literature values for the energy of combustion were combined with the present results to derive entropies, enthalpy increments, and Gibbs free energies of formation for the ideal gas at p = p0 = 101.325 kPa for temperatures between T = 250 K and T ca. 0.95*Tc.Barriers to methyl-group rotation for the ortho-substituted compounds are estimated and compared with literature values for 1,2-dimethylbenzene.
