Thermal behavior and electrochemistry of protic ionic liquids based on triethylamine with different acids

Protic ionic liquids (PILs) composed of the triethylammonium cation with dihydrogen phosphite, tosylate, and trifluoroacetate anions were synthesized. All samples were salts with melting points below 100 °C and were characterized via NMR spectroscopy, attenuated total reflection (ATR) spectroscopy, differential scanning calorimetry (DSC), and thermogravimetry (TG). The electrochemical characteristics of each protic ionic liquid were obtained using a combination of impedance spectroscopy and cyclic voltammetry. Moreover, the influence of water on the thermal behavior and conductivity of triethylammonium tosylate is studied. A linear correlation between the temperatures of melting and crystallization is established for a number of PILs, including both derivatives of triethylamine with different acids reported in the literature and the newly synthesized PILs. The optimal combination of thermal characteristics and electroconductivity was observed for triethylammonium trifluoroacetate and tosylate.

POSITIVE RESIST COMPOSITION AND PATTERNING PROCESS

A positive resist composition comprises (A) a resin component which becomes soluble in an alkaline developer under the action of an acid and (B) an acid generator. The resin (A) is a polymer comprising recurring units containing a non-leaving hydroxyl group represented by formula (1) wherein R1 is H, methyl or trifluoromethyl, X is a single bond or methylene, m is 1 or 2, and the hydroxyl group attaches to a secondary carbon atom. The composition is improved in resolution when processed by lithography.

On the reaction of bis(phosphothioyl)disulfanes with hydroxamic acids, part I: Ionic versus radical reaction pathways

Among sodium N-alkyl-4-chlorobenzohydroxamates treated with bis(phosphothioyl)disulfanes >P(S)SSP(S)P(S) is phosphorothioyl, phosphonothioyl, and phosphinothioyl), only the N-methyl one yields quantitatively the respective O-phosphothioyl derivatives exhibiting complete inversion of configuration at phosphorus in a reaction whose products are inert toward dithiophosphate arising in the reaction. For branched N-alkyl benzohydroxamates, products of a SET process predominated. The mechanism of the title reaction is discussed.

SYNTHESE DE DILACTONES MACROCYCLIQUES ASSISTEE PAR LES ORGANOSTANNIQUES APPLICATION AUX MACROCYCLES SOUFRES (SULFURES, SULFOXYDES, DISULFURES) COMPLEXATION SELECTIVE DE L'ION Ca(2+)

Tin "template driven" condensation of diacid fluorides with triphenyltin derivatives of diols affords macrocyclic dilactones in good yields.The reaction proceeds at moderate dilution conditions from diacids and diols without isolation of the intermediate activated species.The dilution, temperature and ring-size effects on this reaction are detailed.This method is applied to the praparation of sulfur-, disulfide- and sulfoxide-containing macrocyclic dilactones, as well as to the preparation of chiral macrocycles derived from α-aminoacids.The binding abilities of these twelve new ligands (12- to 21-membered rings) are estimated by picra te extraction from water to chloroform.Selective complexation for calcium is found in some cases.
