Influence of Aluminum, Gallium, Indium- Doping on the Boron-Nitride Nanotubes (BNNTs) investigated with density functional theory (DFT) and Hartreefock (HF) methods. For this purpose, the chemical shift of difference atomic nucleus was studied using the gauge included atomic orbital (GIAO) approch. In the following, structural parameter values, electrostatic potential, thermodynamic parameters,...
The syntheses of hydroxymethylenebisphosphonic acid derivatives (dronic acid derivatives) starting from the corresponding substituted acetic acids and P-reagents, mainly phosphorus trichloride and phosphorous acid are surveyed according to the solvents applied. The nature of the solvent is a critical point due to the heterogeneity of the reaction mixtures. This review sheds light on the optimum...
Diglycolyl chlorides, commercially available or obtained from the corresponding dicarboxylic acids, have been converted into the corresponding diamides by reaction with a wide range of amines in an organic-aqueous biphasic system (Schotten–Baumann approach) in high yields. Treatment with poly(4-styrenesulfonic acid) afforded the pure compounds. Substituted diglycolyl diesters, obtained by coupl...
