Kondo chains

The Kondo-lattice Hamiltonian conserves total spin and being an interacting model is nontrivial to solve. However, as with the conjugated systems, it is possible to solve finite Kondo chains efficiently by employing the VB method. The VB... 

These pioneer studies laid dormant until 1977 and, influenced by Kondo and colleagues [59] reports on the synthesis of po]y(vinylsulfonium yiide) with a trivaient sulfur attached directly to the polymer chain, poly[ethyl-vinylsulfonium bis-(methoxycarbonyl) methylide] (Scheme 25) was prepared by irradiation of a benzene... 

Recently, Kondo and coworkers reported on the polymerization of St with diphenyl diselenides (37) as the photoiniferters (Eq. 39) [ 162]. In the photopolymerization of St in the presence of 37a and 37b, the polymer yield and the molecular weight of the polymers increased with reaction time. The chain-end structure of the resulting polymer 38 was characterized. Polymer 38 underwent the reductive elimination of terminal seleno groups by reaction with tri-n-butyltin hydride in the presence of AIBN (Eq. 40). It also afforded the poly(St) with double bonds at both chain ends when it was treated with hydrogen peroxide (Eq. 41). They also reported the polymerization of St with diphenyl ditelluride to afford well-controlled molecular weight and its distribution [163]. 

Based on Watanabe s intermolecular hydroacylation of olefins with aldehydes,348 Kondo and Misudo developed the first ruthenium-catalyzed hydroacylation of 1,3-dienes with aldehydes (Scheme 71). Usually, palladium-mediated hydroacylations of 1,3-dienes with aldehydes give tetrahydropyran and/or open-chain homoallylic alcohol derivatives.350 However, in the present ruthenium-catalyzed transformations, the corresponding /3,7-unsaturated...

Irradiation of PP in inert atmosphere results in similar yields for chain scission and crosslinking [Geymer, 1973]. Because of scission, the intrinsic viscosity of PP initially decreases. At higher doses, >100 kGy, gelation caused by crosslinking has been observed [Black and Lyons, 1959 Kondo and Dole, 1966]. Two factors contribute to this effect (i) the presence of trace amounts of hydroperoxides in the PP, which get consumed in various radiolytic reactions, e.g. ... 

Since double-stranded polymers generally have higher stability than singje-stranded ones, Kondo et al. [51a, b] have synthesized phenoxasilin-containing polyamides 33. Unfortunately these proved to be hardly soluble in amide solvents at all and were even insoluble in concentrated H2SO4. Nevertheless, they were more thermally stable (Tj in the range 477-506 °C) compared with their corresponding open-chain polymers.

Finite size algorithms have been used extensively to study the edge states and systems with impurities, where substantial improvement of the accuracy is needed to characterize the various properties of a finite system. The DMRG method has been applied to diverse problems in magnetism study of spin chains with s > 1/2 [72], chains with dimerization and/or frustration [71, 73, 74], coupled spin chains [71, 75, 76], to list a few. The method has also been used to study models with itinerant fermions [77, 78], Kondo systems[79, 80, 81, 82], as well as coupled fermion chains [83, 84], including doping. Formulations for systems with a single impurity [85, 86] as well as randomly distributed impurities [87] and disorder [88] have also been reported. There has also been a study of the disordered bosonic Hubbard model in one dimension [89]. 

Most of the reactions of laudanosine have been carried out with the racemic mixture obtainable by reduction of quaternary papaverinium salts (p. 36). For instance, Gadamer and Kondo (79) obtained by oxidation with mercuric acetate, veratraldehyde and 4,5-dimethoxy-2-( 3-methyl-aminoethyl) benzaldehyde (XLVI) (or its ring-chain tautomer, laudaline), which resembles cotarnine in its properties. The same products are formed when manganese dioxide is chosen as the oxidizing agent (80). In both...
