Abstract
Reaction of cis-[ReCl(NHC)(CO)(4)] cis-[1] (NHC = NH, NH-substituted saturated cyclic diaminocarbene) with diphosphine (2-FeC6H4)(2)P-CH2CH2-P(C6H4-2-F)(2) 2 yields complex fac-[Re(NHC)(2)(CO)(3)]Cl fac-[3] Cl. Deprotonation of the NH,NH-NHC ligand in fac-[3] Cl with KOtBu leads to an intramolecular nucleophilic aromatic substitution of one fluorine atom from each -P(C6H4-2-F) group by the NHC ring nitrogen atoms with formation of complex fac-[4] Cl bearing a facially coordinated [11]ane-P2CNHC ligand. Reaction of cis-[MnBr(NHC)(CO)(4)] cis-[5] (NHC = NH, NH-substituted saturated cyclic diaminocarbene) with diphosphine 2 yields complex [MnBr(NHC)(2)(CO)(2)] [6] without substitution of the bromo ligand and with the phosphine donors from the bidentate diphosphine occupying one cis and one trans position to the NHC donor.
