ACTIVE-OX. Oxidative C-H bond activation in light alkanes by Ag(II) salts containing weakly coordinating anions

The objective of this project is a reactivity reconnaissance of three silver compounds which are very strong oxidants: silver(II) sulphate(VI) monohydrate Ag(II)SO4 x H2O, silver(II) fluorosulphate(VI), Ag(II)(SO3F)2 and silver(II) triflate Ag(II)(SO3CF3)2 towards the model of organic compounds with previously known low reactivity: n-hexane and cyclohexane and light aliphatic hydrocarbons, in particular methane and alicyclic hydrocarbons small rings, as well as their derivatives. All three compounds should have greater electron affinity energies than tested so far silver(II) sulphate(VI), Ag(II)SO4 which, as has recently proved has been capable to activate C-H bond in derivatives of aromatic hydrocarbons. Significant increase of the oxidising ability by transition from sulphate(VI) (dianion) to compounds containing weaker coordinating ligands (fluorosulphate(VI) and triflate monoanions and electrically neutral water molecules) should results of fruitful attack on C-H bond in the aliphatic derivatives.
