The Shilov system was discovered by Alexander E. Shilov in 1969-1972 while investigating H/D exchange between isotopologues of CH and HO catalyzed simple transition metal 
coordination complexes.  The Shilov cycle is the partial oxidation of a hydrocarbon to an alcohol or alcohol precursor (RCl) catalyzed by PtCl in an aqueous solution with [[Platinum(IV) chloride|[PtCl]]] acting as the ultimate oxidant.  The cycle consists of three major steps, the electrophilic activation of the C-H bond, oxidation of the complex, and the nucleophilic oxidation of the alkane substrate.  An equivalent transformation is performed industrially by steam reforming methane to syngas then reducing the carbon monoxide to methanol.  The transformation can also performed biologically by methane monooxygenase.
