The reaction proceeds via two stages: rapidly established equilibrium between the reactants and their molecular complex 1 : 1 [K = (1.97 ± 0.52) × 10 4 L/mol] followed by slow irreversible displacement of hydroxy group into the second coordination sphere to form cationic outer sphere complex (k = 0.26 L s-1 mol-1). The effect of fullerene fragment on pyridine fragments coordination has been considered.

The product structure and ratio were determined by 1H and 13C NMR spectra, X-ray analysis, and GC/MS data. The reductive cyclization of 2-(2-nitrophenoxy)cyclohexan-1-one and 2-(4-methyl-2-nitrophenoxy)cyclohexan-1-one has been shown to produce 2,3,4,4a,10,10a-hexahydro-1H-phenoxazine and its 8-methyl analog as mixtures of stereoisomers with trans and cis-junction of the cyclo-hexane and morpholine rings at ratios of 1:3 and 3:1, respectively.

In the work reported here, we investigated the anchoring of Pd(II), using the method of substitution of competing ligands, and the catalytic properties of the resulting products in p-nitrochlorobenzene hydrogenation. EXPERIMENTAL The polymeric supports were obtained by gas-phase graft polymerization (in the case of the polyethylene-graft-polyvinylcarbazole PE-gr-PVCz by liquid-phase graft polymerization) of the monomers 4-vinylpyridine 4-VP, allylamine AA, acrylonitrile AN, vinylpyrrolidone VPr), or vinylimidazole VIA on the surface of powdered PE (Ssp = 4 m2/g), following procedures given in [5]. The monomers used for the grafting were purified by standard procedures. The content of grafted fragments was determined by gravimetric and chemical methods. The PdCI2(C6HsCN)2 was prepared in accordance with [6]. The Pd(II) was deposited on the polymeric support from a benzene solution, using excess PdCI2(C6HsCN) 2 and a suspension of the polymeric support, with vigorous stirring of the system for 30-60 min at 293-300~ The product was separated by filtration and washed with benzene to remove unbonded Pd(II). The powders that were obtained, yellow to dark brown in color, were insoluble in organic solvents and unaffected by atmospheric oxygen or moisture. The content of Pd(II), which ranged from 0.71% to 2.4% by weight, was determined by nonflame atomic absorption spectrometry in a Saturn instrument. The IR spectra were recorded in a Perkin-Elmer 325 instrument, using samples in the form of tablets with CsI. The x-ray photoelectron spectra were recorded in a Varian IEE-15 spectrometer with a high-intensity magnesium anode [4].

The kinetics of arylsulfonation of the resulting alkylarylamines with benzenesulfonyl chloride and its monosubstituted derivatives in 2-propanol at 298 K were studied. The activation parameters of the reaction of ring-substituted N-isobutylanilines with 3-nitrobenzenesulfonyl chloride were determined.
