Thermodynamic behavior of alkanes in superacid media

Homogeneous Oxidation of Alkanes by Electrophilic Late Transition Metals

“…Furthermore, the redox properties of alkanes are dramatically affected by strong acid solvents. [2,89,90] Thus, while the outer-sphere oxidation of alkanes by Hg II does not initially appear plausible, the reaction conditions may, in fact, promote such a pathway. In a more recent development, [91] the reaction in Equation (13) is catalyzed even more efficiently by a bipyrimidine complex of Pt II (8): At 200 8C in fuming sulfuric acid, methyl bisulfate can be obtained in over 70 % yield based on methane (90 % conversion, 81 % selectivity).…”

[Co(CO)5][(CF3)3BF]: A Stable Salt of a Homoleptic Trigonal‐Bipyramidal Metal–Carbonyl Cation

“…[3][4][5][6] In particular SbF 5 , the strongest molecular Lewis acid [7,8] and the conjugate Brønsted--Lewis superacid HF-SbF 5 , [1,2] have allowed the formation of a substantial number of salts with superelectrophilic, [9] …”

Pentane transformations over sulfated alumina catalyst

“…In the presence of such catalysts, pentyl cation undergoes deprotonation to pentene, which would react with another pentyl cation to form a dimeric cation. After isomerization and subsequent b-scission, the dimeric cation produces both 2-methylpropane and 2-methylbutane [4,5]. The remaining unsaturated decomposition reaction products became coke precursors.…”
