The synthesis and characterization of spiro5,5-dimethylcyclohexane1,2,3-trione2-phenylhydrazone, phenylazodimedone (AD) and the characterization of its complexes with Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) have been carried out. AD was found to have the hydrazone form with intra-...
The overall enthalpy of s-H hydrate formation has been evaluated using the Clapeyron equation. The transition enthalpy change from s-H to s-I is estimated to be about 70 kJ/mol for unit amount of s-H hydrate. Neither cis-1,3-dimethylcyclohexane nor cis-1,4-dimethylcyclohexane generates ...
Crystal structure of 2-((dimethylamino)methylene)-5,5-Dimethylcyclohexane-1,3-dione, C11H17NO2C11H17NO2, monoclinic, P2(1)/c (no. 14), a = 5.9245(2) angstrom, b = 17.7243(6) angstrom, c = 10.2915(4) angstrom, beta = 95.352(1)degrees, V = 1075.97(7) angstrom(3), Z = 4, ...
The gas-phase molecular structure of 1,1-dimethylcyclohexane has been investigated by the electron diffraction technique. The results confirm the prediction of valence force calculations, viz., axial substitution causes a flattening (Φav = 51.7°) of the chair form of the cyclohexane ring....

The compounds are shown to not exhibit cytotoxic properties in the studied concentration range (1-50渭M). Antibacterial, protistocidal, and fungistatic properties of HL, its structural analogue 2-anilinomethylidene-5,5-dimethylcyclohexane-1,3-dione (HL 1 ), and complexes on their base are ...
Catalytic tests showed high activity of complexes 1 and 2 as precatalysts in homogeneous oxidations of alkanes (cyclohexane, methylcyclohexane, n-heptane, cis-1,2-dimethylcyclohexane with hydrogen peroxide in acetonitrile solution. Hydroxyl radicals take part in the reaction. The same complexes catalyze...
