Abstract:A kinetically stabilized 1,3,6-triphosphafulvene displayed regioselective reactivity toward nucleophiles at the external phosphorus atom (position 6) to afford the corresponding phosphinodiphospholide anions, which gave phosphinodiphospholes after quenching with electrophiles, as well as being readily reduced by sodium naphthalenide suggesting properties similar to fulvenes.
Keywords:Phosphaalkenes  Conjugated system  Nucleophilic reaction  Reduction  Regioselectivity
