An unprecedented rearrangement of 1,2-bis(sulfone)vinylenes used in aminocatalysis led to the formation of highly useful gem-disulfones. By using aminal-pyrrolidine organocatalysts, the 1,2-sulfone shift was generalised, leading to highly versatile adducts using both ketones and aldehydes. It represents a valuable alternative for the -alkylation of carbonyl compounds.
