Preparation and organometallic complexes of the new unsymmetrical ligand: Ph2PNHC6H4PPh2
Deprotonation of (2-diphenylphosphino)benzeneamine with BuLi followed by reaction with ClPPh2 in THF gave Ph2PNHC6H4PPh2 in good yields. The new unsymmetrical ligand has been incorporated into a number of complexes [[Rh(Ph2PNHC6H4PPh2)(cod)][ClO4] 2, RhCl2(eta(5)-C4Me5) (Ph2PNHC6H4PPh2-P-(N)) 3, [Rh...

Summary: | Deprotonation of (2-diphenylphosphino)benzeneamine with BuLi followed by reaction with ClPPh2 in THF gave Ph2PNHC6H4PPh2 in good yields. The new unsymmetrical ligand has been incorporated into a number of complexes [[Rh(Ph2PNHC6H4PPh2)(cod)][ClO4] 2, RhCl2(eta(5)-C4Me5) (Ph2PNHC6H4PPh2-P-(N)) 3, [RhCl(eta(5)-C5Me5) (Ph2PNHC6H4PPh2-P(N)P)][Cl] 4, IrCl2(eta(5)-C5Me5) (Ph2PNHC6H4PPh2P(N)) 5, RuCl2(eta(6)-(MeC6H4Pr)-Pr-i) (Ph2PNHC6H4PPh2-P-(N)) 6, [RuCl(eta(6)-Me-(C6H4Pr)-Pr-i) (Ph2PNHC6H4PPh2-P-(N),P)][BF4] 7, RuCl2(eta(6)-C6Me6) (Ph2PNHC6H4PPh2-P-(N)) 8, [RuCl(eta(6)-C6Me6) (Ph2PNHC6H4PPh2-P-(N),P)][BF4] 9, RuCl2(eta(3):eta(3)-C10H16) (Ph2PNHC6H4PPh2-P-(N)) 10, OsCl2(eta(6)-(MeC6H4Pr)-Pr-i)(Ph2NHPC6H4PPh2-P-(N)) 11] to demonstrate its coordination behaviour as a monodentate or as a chelate ligand. The X-ray structures of for 5, 9 and 10 are reported. (C) 1999 Elsevier Science S.A. All rights reserved. |
