WebGiovanni Piancatelli The arylation of 5-halogenothiophene-2-carbonitrile and methyl 5-halogenothiophene-2-carboxylate by a photochemical process was investigated. WebPiancatelli rearrangement can be rationalized in one of two ways. First, ring-opening of the aminal 4 may be the rate-limiting step in the catalytic cycle. The analogous spirocyclic acetal species have been isolated in the oxa-Piancatelli reaction and were found to be stable and catalytically competent.3,9
