• In the presence of a free-radical initiator, can be used in a tin-free procedure for alkyl radical reactions: Angew. Chem. Int. Ed., 43, 3598 (2004).
•
Useful intermediate in multicomponent reactions. For example, forms a reactive 1 : 1 adduct with acetylenic esters, e.g. Dimethyl acetylenedicarboxylate, A11437, which can be trapped with strong C-H acids, such as 4-Hydroxy-6-methyl-2-pyrone, L11457:
