Reaction of the dimers [{(η5-C5Me5)MCl}2(μ-Cl) 2] (M = Rh, Ir) or [{(η6-arene)RuCl}2(μ-Cl)2] (arene = p-MeC6Hi4Pr, C6Mesub

Reaction of the dinuclear complexes [{Pd(μ-Cl)(L-L)}2] (L-L = C9H12N or C12H12N), [{Pt(μ-OMe)-(C8H12OMe)}2], [{RuCl(μ-Cl)(η6-p-MeC6H4Pri)} 2] or [(RhCl(μ-Cl)(η5-C5Me5)}2] with K[Ph2P(E)NP(E)Ph2] (E = S or Se) in thf gave the corresponding bridge cleaved, mononuclear compounds [Pd(L-L)(Ph2P(E)NP(E)-Ph2-E,E′}], [Pt(C8H12OMe){Ph2P(E)NP(E)Ph 2-E,E′}], [RuCl{Ph2P(E)NP(E)Ph2-E,E′}(η 6-p-MeC6H4Pri)] or [Rh(η5-C5Me5)Cl{Ph 2P(E)NP(E)Ph2-E,E′}] in high yields (64-97%). Transmetallation of K[Ph2P(E)NP(E)Ph2] (E = S or Se) with [{Pd(μ-Cl)(η3-C3H5)}2] in a 1:1 ratio gave [Pd(η3-C3H5){Ph2P(E)NP(E)Ph 2-E,E′)]. In contrast, reaction of the potassium salt K[Ph2P(O)NP(E)Ph2] (E = S or Se) with [{Pd(μ-Cl)(η3-C3H5)}2] under analogous conditions gave instead the dimeric species [{Pd(η3-C3H5)[Ph 2P(O)NP(E)Ph2-E]}2]. All new compounds have been characterised by a combination of multinuclear NMR [1H, 31P-{1H}, 195Pt-{1H}] and IR spectroscopy, elemental analyses and in four cases by single crystal X-ray crystallography. The six-membered ME2P2N metallacycles [Pd(C9H12N)(Ph2P(Se)NP(Se)Ph 2-Se,Se′)], [Pt(C8H12OMe){Ph2P(S)NP(S)Ph 2-S,S′}] and [Pd(η3-C3H5)(Ph 2P-(S)NP(S)Ph2-S,S′)] all adopt pseudo-boat conformations. In contrast [{Pd(η3-C3H5)[Ph 2P(O)NP(Se)Ph2-Se]}2] is binuclear with a central four-membered Pd2Se2 core and two pendant P(O)Ph2 moieties. The synthesis, characterisation and preliminary complexation studies of a new potassium salt, K[Ph2P(S)NP(Se)Ph2], prepared by deprotonation of Ph2P(S)NHP(Se)Ph2 with KOBut are also described.
