The iminophosphorane-phosphane Ph2PC6H 4OC6H4PPh2=NP(O)(OPh)2: Synthesis, reactivity, and catalytic activity in Suzuki cross-coupling and the homogeneous hydrogenation of olefins

The iminophosphorane-phosphane ligand Ph2PC6H 4OC6H4-PPh2=NP(O)(OPh)2 (1) has been synthesized by partial imination of bis[2-(diphenylphosphanyl) phenyl] ether (DPEphos) with phosphoryl azide (PhO)2P(O)N 3. A similar reaction in a 1:2 stoichiometry affords the bis(iminophosphorane) O-{C6H4PPh2=NP(O)(OPh) 2}2 (2). The chalcogen derivatives O{C6H 4P(E)Ph2}2 [E = S (3) and Se (4)] and Ph 2P(E)-C6H4OC6H4PPh 2=NP(O)(OPh)2 [E = S (5) and Se (6)] are also synthesized by treating DPEphos and 1 with elemental sulfur and selenium, respectively. The mononuclear complexes trans-[MCl2{κ1-P-Ph 2PC6H4OC6H4PPh 2=NP(O)(OPh)2}2] [M = Pt (7) Pd (8)] and trans-[Rh(CO)Cl{κ1-P-Ph2PC6-H 4OC6H4PPh2=NP(O)(OPh) 2}2] (12) are prepared by the reaction of 1 with [Pt(COD)Cl2], [Pd(COD)Cl2], and [{Rh(CO) 2-Cl}2], respectively. Treatment of 1 with [Pd 2(dba3)] (dba = dibenzylideneacetone) affords the mononuclear complex [Pd0{κ2-P,O-Ph 2PC6H4OC6H4PPh 2=NP(O)(OPh)2}2] (9) in which ligand 1 coordinates through its P and O centers in a κ2-P,O chelating fashion. The monocoordinated AuI complex [AuCl{κ1-P- Ph2PC6H4OC6H4PPh 2=NP(O)(OPh)2}] (10) has been prepared by the reaction of 1 and [AuCl(SMe2)] and its structure has been confirmed by X-ray crystallography. The reaction of 1 with [{Rh(COD)Cl}2] in the presence of AgOTf affords the cationic RhI complex cis-[Rh(COD){κ2-P,O-Ph2PC6H 4OC6H4PPh2=NP(O)(OPh) 2}][OTf] (11). The catalytic activity of the Pd0 complex 9 has been investigated in Suzuki cross-coupling reactions. Homogeneous catalytic hydrogenation of olefins has also been studied using the cationic Rh I complex 11. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
