title: Synthesis of phosphole-2,5-dicarboxylic acids via a [1,5]-shift of carbon dioxide around the phosphole nucleus.
abstract: A new methodology for the synthesis of 1-P-functionalized phosphole-2,5-dicarboxylic acids is described. The carboxylic group is introduced through a two-step sequence which involves a preliminary attack of the phospholide unit onto CO(2) followed by a [1,5]-shift reaction of the CO(2)Li group around the phosphole nucleus. This approach was extended to the preparation of a new type of bidentate ligands. [reaction: see text]
