3-chloro-3-methyl-2-butanone in ethanolic KOH at room temperature gave 3,3-dimethyl-5-aryltetrahydro-2-furanone as a major product. The reaction can be tentatively explained by the combination of Favorskii rearrangement and aldol reaction.

Electrochemical hydrocarboxylation and deuterocarboxylation of allenes and carbon dioxide were achieved with H2O and D2O, respectively. This reaction generally affords good to excellent regioselectivity in the formation of diverse carboxylic acids.
