This short review provides an overview of the recent advances in the direct transformation
of propargyl alcohol derivatives to allenes, benefiting from the merger of transition
metal and photoredox catalytic systems. Two main strategies are discussed and organized
around the mode of activation of the propargyl electrophile C–O bond, i.e., catalytic
methods either involving oxidative addition or photoinduced homolytic cleavage as
the key elementary steps.
