An efficient procedure for the preparation of allylic trifluoromethanesulfones with high regioselectivity from aromatic allylic alcohols/esters and NaSO2CF3 under transition-metal-free conditions is described. A wide range of functional groups were tolerated. This is the first example to realize different types of allylic alcohols, including primary, secondary, and tertiary allylic alcohols, all of which transferred to the corresponding products efficiently in good to excellent yields with readily available and inexpensive NaSO2CF3. The synthetic utility of the method was demonstrated by performing the reaction at gram scale.

A protocol for the synthesis of α,β-unsaturated aldehydes and allylic alcohols from simple allylic hydrocarbons with water via palladium-catalyzed functionalization of allylic C?H bonds was described. Molecular oxygen is utilized as the sole oxidant in this oxygenation of terminal alkenes. This protocol features good functional group compatibility, broad substrate scope, and high atom- and step-economy. Moreover, the synthetic utility of this method can be highlighted by its application to the synthesis of ibuprofen, which is a highly potent analgesic. (Figure presented.).
