Abstract: The chromic acid oxidation of secondary cyclopropanols is IO3 to IO6 times faster than that of other secondary aicohols. Tertiary cyclopropanols are even more reactive with l, 2, 2, 3, 3-pentamethylcyclopropanol being the most reactive organic compound known toward this oxidant. The free hydroxyl group is a necessary prerequisite for the high reactivity; cyclopropyl alkyl ethers and cyclopropyl esters are relatively unreactive. Only ...
