Palladium-catalysed reduction of heteroaromatic naphthyl ethers: Structural effects on reactivity

Tetrazolyl and benzisothiazolyl naphthylmethylic ethers 3 and 4(a-e) are stable crystalline compounds that can be synthesised in high yields by reaction of the corresponding naphthyl methanols (1a-e) with the derivatizing agents 2a and 2b. Experimental conditions for palladium-catalysed hydrogenolysis of ethers 3, 4, with a hydrogen donor and with molecular hydrogen, were investigated. Analysis of the structure and reactivity indicates that naphthylmethylic ethers 3 and 4 are structurally similar to the corresponding benzyloxyderivatives around the ether bond but exhibit different reactivity. Structural analysis for these compounds is based on crystallographic structure determinations, for 5-(2-naphthylmethoxy)-1-phenyltetrazole (3a) and 3-(2-naphthylmethoxy)-1,2- benzisothiazole 1,1-dioxide (4a), and molecular orbital DFT(B3LYP)/6-311G(d) calculations, for all ethers. It can be concluded from this investigation that 5-chloro-1-phenyltetrazole 2a acts as a better derivatizing agent for naphthyl methanols than 3-chloro-1,2-benzisothiazole-11-dioxide 2b, this contrasting with what has been observed with phenols, allylic and benzylic alcohols.

The effect of intermolecular forces on the glass transition of solute-polymer blends: 2. Extension to different solutes

The effects of intermolecular forces on the glass transition temperature (Tg) of various dye solutes in numerous polymer matrices have been investigated. The Tgs of these dye-polymer blends were found to depend on the polymer Tg, the dye Tg, their relative concentrations and the dye-polymer affinity. Attempts have been made to correlate increases in Tg with dye-polymer affinity using solubility parameters as a predictive tool. Poor correlations were obtained using global solubility parameters. Excellent correlations were made between elevation in Tg and enhanced dye-polymer affinity using averaged polar/hydrogen bonding solubility parameters. For all dye solutes, the Tg was low when there was a large mismatch in solubility parameters, increased as dye and polymer became more compatible and was at a maximum when the solubility parameters of both components were equal. The results also indicate that longer range polar and hydrogen bonding forces have a controlling influence on Tg.

Bismuth(III) saccharinate and thiosaccharinate complexes and the effect of ligand substitution on their activity against helicobacter pylori

Five bismuth(III) saccharinate and thiosaccharinate complexes, [Ph 2Bi(sac)]?1, [Bi(sac)3]n2, [Ph2Bi(tsac)]?4, [PhBi(tsac)2] n5, [Bi(tsac)3]n6 (sacH = saccharin, tsacH = thiosaccharin), have been synthesized and fully characterized. The tendency for ligand redistribution in [Ph2Bi(sac)]? has been investigated in solution by NMR spectroscopy. The structures of [Ph 2Bi(sac)]?1 and [Ph2Bi(tsac)] ?4 have been confirmed by X-ray crystallography. In Ph 2Bi(sac) the sac ligand is bound to a four-coordinate bismuth center via its imino nitrogen atom with an accompanying long-range Bi-O interaction. However, in the structure of [Ph2Bi(tsac)]? the ligand is sigma-bound through the exocyclic sulfur atom, giving a thiolate complex, confirming the more thiophilic nature of bismuth(III). Both complexes consist of polymeric chain structures with formally four-coordinated bismuth atoms. The complexes were assessed for their activity against H. pylori. The activity is both ligand dependent and sensitive to the degree of ligand substitution. The saccharinate complexes, 1 and 2, show activity comparable with standard tris-carboxylato bismuth(III) compounds, 6.25 mug/mL, while the activity of the thiolato complexes, 4-6, increases dramatically on increasing the number of thiolate groups from one to three (range 50-6.25 mug/mL). Saccharin, thiosaccharin, and BiPh3 were found to be inactive.
