Abstract
The halogenation of 2-phenylethanol-1-14C and -1-13C was carried out with halogenphosphorus or phosphorus trihalide under various conditions. The resulting 2-phenylethyl halides showed isotopic scrambling of the 14C and 13C label from C-1 to C-2. The degree of rearrangement increased with the rise of reaction temperature. In a given temperature, the rearrangement in iodination was more than that found in bromination or chlorination.
