Trisubstituted Cyclohexanes / Trisubstituted Cyclohexanes

open access: yesZeitschrift 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.

Selectivity and efficiency of pyrene attachment to alkanes induced by broadband X-rays

open access: yesAnais 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.
