title: Oxidative carboxylation of arylaldehydes with water by a sulfoxylalkyl-substituted N-heterocyclic carbene catalyst.
abstract: The N-Heterocyclic carbene-catalysed oxidative carboxylation of arylaldehydes with water successfully proceeded when a sulfoxylalkyl-substituted imidazolium salt was used as the catalyst. The reactions can be run in the absence of oxidant, and a variety of arylaldehydes having an electron-withdrawing group were converted to the corresponding carboxylic acids.
