Not only symmetrical, but also unsymmetrical α,α-diaryl allylic alcohols are employed as substrates in the title reaction. A number of arenes and even heteroarenes underwent radical 1,2-aryl migration ("neophyl rearrangement") to produce α-aryl β-trifluoromethyl ketones. The preferential migration of electron-deficient aryl groups over electron-rich ones in unsymmetrical substrates supports the radical mechanism, which was further confirmed by DFT calculations.

BLA=0? Not so fast! A series of tetraarylcumulenes up to the length of a [9]cumulene has been synthesized and analyzed by X-ray crystallography. The structural data show a distinct reduction in bond-length alternation (BLA) as a function of molecule length, but this trend appears to reach a limit before a cumulenic structure with BLA=0 is achieved.
