Résumé : The thermal cracking of ortho and para-cresols labelled in specific position with [14C] and [3H] shows that the formation of water and methane are directly related to the formation of toluene and phenol respectively. On the other hand, the formation of benzène results from a rearrangement to a cycloheptatriene followed by elimination of carbon monoxide, produced quasi exclusively by loss of the carbon supporting the hydroxyl function. The minor products involve either a C5 intermediate (cyclopentadiene), or a C6 analogue (methylcyclopentadiene). The carbon supporting the hydroxyl group is not involved in the formation of minor products. © 1975.
