Chromic acid oxidation of hydrocarbons has been intensively studied. In general, for aliphatic hydrocarbons, the relative rates of oxidation in primary, secondary, and tertiary CH positions are 1: 110: 7000.2 Although considerable data exist concerning the oxidation of aromatic-aliphatic systems. 3 very little information is available on oxidation of hydrocarbons containing nonequivalent benzylic positions capable of competing for the oxidizing agent. ...
