Quantitative Yield

Catechol reacts with boron sulfide to give 2,2′-o-phenylenedioxybis-(1,3,2-benzodioxaborole) (1) while only the hydroxyl function of salicylic acid reacts to give a quantitative yield of tris(o-carboxylphenoxy)borane (3). Phthalic acid is dehydrated to phthalic anhydride, but succinic acid and maleic acid have been found inert to the action of the boron sulfide.

The aqueous phase hydrogenation of maleic acid to succinic acid (SAc) is proved using an efficient and robust Pd/C catalysts and stoichiometric formic acid as source of H2. SAc can be separated from the reaction medium by precipitation.

AbstractIn this article nanoscaled polyanilines (PANI) were prepared based on template-free method in the presence of dicarboxylic acid dopants (e.g. D-tartaric acid, succinic acid, maleic acid and fumaric acid). The trans-cis isomerization of butenedioic acid played an important role in the formation of nanostructures from the plane-like to nanofibers, and the PANI doped with maleic acid (MA) had larger diameter, higher crystallinity and conductivity than PANI doped with fumaric acid (FA).

Acetylenedicarboxylic Acid

Approaches to the synthesis of diselenols have led to isolation of several new organoselenium compounds. Removal of mercury, as HgS, from [1,3-diselenylpropan-2-olato(2–)-Se,Sel]-mercury(II) results in decomposition of the organoselenium fragment to selenetan-3-ol, 1,3-Dibromopropan-2-ol reacts with KSeCN to form 1-bromo-3-selenocyanatopropan-2-ol; the selenoethers 2-(benzyl- se1eno)fumaric acid [(Z)-PhCH2SeC(CO2H)=CHCO2H] and 2-(benzylseleno)succinic acid [PhCH2SeCH(CO2H)CH2CO2H] are formed by base-catalysed reaction of phenylmethaneselenol with acetylenedicarboxylic acid and maleic acid, respectively. The conformations adopted by PhCH2XCH(CO2H)CH2CO2H (X = S, Se) in acetone have been determined by 1H n.m.r. spectroscopy.

With an average diameter of 148-285 nm and a conductivity of 2.38E-2- 5.88 E-2S/cm, Nanoscaled polyaniline (PANI) were synthesized based on template-free method in the presence of dicarboxylic acids dopants (e.g., D-tartaric acid, Succinic acid, maleic acid and fumaric acid). Furthermore, the trans-cis isomerization of butenedioic acid plays an important role in the formation of nanostructures from plane-like to nanofibers, and PANI-MA has larger diameter, higher crystallinity and conductivity than PANI-FA.
