Novel Ring Systems: Spiro[Cycloalkane] Derivatives of Triazolo- and Tetrazolo-Pyridazines
Molecules, 2021 In orderto synthesize new pyridazine derivatives anellated with different nitrogen heterocyclic moieties, spiro[cycloalkane]pyridazinones were transformed into the corresponding thioxo derivatives via a reaction with phosphorus pentasulfide. The reaction

Entropy scaling based viscosity predictions for hydrocarbon mixtures and diesel fuels up to extreme conditions [PDF]
, 2019 An entropy scaling based technique using the Perturbed-Chain Statistical Associating Fluid Theory is described for predicting the viscosity of hydrocarbon mixtures and diesel fuels up to high temperatures and high pressures. The compounds found in diesel

Trisubstituted Cyclohexanes / Trisubstituted Cyclohexanes
Zeitschrift für Naturforschung B, 1985 C-Tertiarv vinylketones or the corresponding masked vinylketone derivatives react with pyrrolidin-2-one in the system sodium hydride.dimethylsulfoxide to substituted cyclohexanes of the 1,3.5- and sometimes additionally of the 1,2.4-type. Only acetophenone Mannich bases bearing a p-hydroxy or a dimethylamino group failed in cyclization.

Highly alkylated cyclohexanes. X-Ray crystal structures, force-field calculations, and conformations of cis/trans-1,4-disubstituted cyclohexane isomers [PDF]
, 1988 The structures of mesylated cis- and trans-tetramethylshisool cis- 2 and trans-2 have been elucidated by single-crystal X-ray techniques. In cis-2 the isopropenyl group adopts an axial position in the crystal, and the structural data obtained are in good
