Transient 2H-phospholes as powerful synthetic intermediates in organophosphorus chemistry

Article Abstract:

Cyclopentadienes, 2H-phospholes can act both as dienes and dienophiles. 2H-phospholes can readily deprotonated to give highly aromatic anions and can readily react with transition metal derivatives to give n5-complexes representing a diagonal phosphorus-carbon analogy.
