The π-electron delocalization in the diazaphospholenes 1 leads not only to a weakening of the P-H bond, but also to an umpolung of its reactivity. Thus, compounds 1 react with acids with elimination of H2, and display an inverse regioselectivit
Novel aspects of phosphorus analogues of arduengo carbenes: From very stable phosphenium ions to umpolung of P-H bonds

According to the results of structural and computational studies, P-halogeno-diazaphospholenes are not ionic but feature weak and polar covalent P-X bonds. Similar bond weakening effects which are attributable to l.p. (N)-σ*(P-X) hyperconjugation were als
