The l,X-naphthyridines react with phenyllithium to afford the corresponding 2-phenyl derivatives.32 When 1,8-naphthyridine is treated with butyl-lithium, the 2-butyl derivative is obtained, whereas reaction of dithiane with butyl lithium followed by addition of 1,8-naphthyridine generates bisnaph-thyridine 49. An interesting application of the dimethyl sulfoxide-sodium...

Streitwieser et al. [160] and BordweU et al. [161] used the lyate ions of organic solvents such as cyclohexylamine and dimethyl sulfoxide in the determination of the C—H acidity of weak organic carbon acids. Using super base systems such as alkali metal salts of cyclohexylamine [i.e. lithium and cesium cyclohexylamides) [160] and dimethyl sulfoxide (sodium dimsyl) [161] in an excess of these non-HBD solvents, relative acidity scales for weak carbon acids have been established. In this way, values for the ionization of over a thousand Bronsted acids in dimethyl sulfoxide have...

Other electrolytes that have been applied, are dimethyl sulfoxide/sodium hydride, glycol methyl ether/water/potassium carbonate or acetic acid/potassium carboxylate. ... 

The conventional dienone-phenol rearrangements of o-quinol acetates are described above. An alternative mode of restructuring to an aromatic system has been observed, exemplified by the quantitative conversion of the 2,4-dienone (155) on heating at 110 C in acetic acid to the benzylic acetate (156). The related 2,4-dienone (157) rearranges at 70-80 °C in dimethyl sulfoxide-sodium bicarbonate to the...

NMR spectroscopy has been applied to the determination of ester groups in polyethylene terephthalate (PET) [45]. A blend of a protic solvent (dimethyl sulfoxide), sodium hydroxide, and methanol hydrolyses ester groups in this polymer much more rapidly than do hydrolysis reagents previously used.
