A Lewis acid promoted Csp(3)-H bond functionalization of methyl azaarenes with alpha-trifluoromethylated carbonyl compounds is described. Catalytic amounts of Yb(OTf)(3) provided a straightforward access to the corresponding trifluoromethylated alcohols in excellent yields up to 94% under mild reaction conditions.
