Selectivity and efficiency of pyrene attachment to alkanes induced by broadband X-rays
Anais da Academia Brasileira de Ciências, 2003 Bombardment of pyrene-doped n-heneicosane (C21H44) in its orthorhombic solid phase with MeV broadband X-rays results in the formation of both mono- and di-heneicosylpyrenes, whereas the same dose in liquid cyclohexane yields only monosubstituted pyrene.

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.

Crystal structure of 2-cyclohexyl-1,3-thiazolo[4,5-b]pyridine
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, C12H14N2S, the cyclohexane ring adopts a chair conformation with the exocyclic C—C bond in an equatorial orientation. The mean plane through the cyclohexane ring (all atoms) is twisted from the thiazolopyridine ring system (r.m.s ...
