Temperature dependences of the saturated vapor pressure of lanthanum complexes based on 2-(2-benzoxazol-2-yl)phenolate ligand have been obtained using the Knudsen effusion method. The thermodynamic parameters of vaporization have been calculated from the p−T data. Mass spectra and differential scanning calorimetry data have been obtained.

The reaction of potassium 4-aminobenzoate with 2-bromomethyl-1,1-dichlorocyclopropane proceeds regioselectively with the retention of a three-membered ring and leads to the formation of 2,2-dichlorocyclo-propylmethyl 4-aminobenzoate. The reaction of 2,2-dichlorocyclopropylmethyl 4-aminobenzoate with maleic anhydride and intramolecular cyclization o...

The formation of a thermotropic smectic phase in 3,5-diamino-1-dodecyl-1,2,4-triazole was revealed by polarizing microscopy and DSC. Depending on heating and cooling conditions, transitions between different types of layered packings occur, which was evidenced by dielectric measurements. Quantum-chemical simulation established that the mesomorphism...
