By making use of a novel diastereotopicity probe, namely C(CF 3)2OH, it has been possible to measure by very low temperature19F NMR spectroscopy the elusive aryl-aryl rotation barriers of biphenyls bearing an OH or F group in one ortho position. The experimental values (5.4 and 4.4 kcalmol-1, respectively) are matched by those from ab initio calculations (5.3 and 4.3 kcalmol-1, respectively).
