Peculiarity of aqueous solutions of 2,2,2-trifluoroethanol.

Aqueous solutions of 2,2,2-trifluoroethanol appear to show a structural transition at alcohol mole fraction equal to x(TFE) = 0.05, which can be concluded from a discontinuity of the speed of sound. At the same concentration, a discontinuity was observed in the parameters of the long-living component of the positron annihilation spectrum.

Synthesis of 1-{4-[4-(adamant-1-yl)phenoxymethyl]-2-(4-bromophenyl)- 1,3-dioxolan-2-ylmethyl}imidazole with expected antifungal and antibacterial activity.

A multistep synthesis of a new analogue of ketoconazole, which was expected to show antifungal and antibacterial activity, has been described.
