An efficient entry to monoiminophosphoranes derived from 1,2-bis(diphenylphosphino)ethane: new bidentate P,N ligands
摘要:
Base-catalyzed Michael-type addition of diphenylphosphane to P,P,P-diphenylvinyl iminophosphoranes yielded monoiminophosphoranes derived from 1,2-bis(diphenylphosphino)ethane, heteroditopic P,N-donor ligands which are not easily available by the direct monoimination of the parent bis(phosphane).

yielded the cationic complexes 5 with the ligands coordinating in a N,N′,N′-terdentate fashion. Additionally, by the use of other nucleophiles such as diphenylphosphane and thiophenol this methodology has been applied to the synthesis of the new N,P-(R–NP(Ph2)CH2CH2PPh2) (9) and N,S-bidentate (R–NP(Ph2)CH2CH2SPh) (10) ligands, respectively, and of their corresponding Pd(II) complexes (11 and 12).
