(NPPh2)[NP(OCH2CH2CH═CH2)2]2 (9) and (NS(O)Ph)[NP(OCH2CH2CH═CH2)2]2 (10) with the same catalyst resulted in the formation of 11-membered diansa compounds NPPh2[NP(OCH2CH2CH═CHCH2CH2O)]2 (11) and (NS(O)Ph)[NP(OCH2CH2CH═CHCH2CH2O)]2 (13) and the intermolecular doubly bridged ansa−dibino−ansa compounds 12 and 14. The X-ray structural studies of compounds 11 and 13 indicated that the double bonds of the ansa-substituted
