	abstract = {The NHC-Rh-I complexes [RhCl(COE)(NHC)](2) 1 and 2 [COE = cyclooctene, NHC in 1 = N,N-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) and, in 2, N,N-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene (IMes)] react with H-2 in hexane to give the dimeric, mono-carbene dihydrido species [Rh(H)(2)Cl(NHC)](2) (NHC = IPr (3), IMes (4)). In the presence of further NHC, the bis-carbene dihydrido species Rh(H)(2)Cl(NHC)(2) are formed; a crystal structure of the IPr complex 5 is analogous to that of the known IMes analogue. The dihydride-mixed-carbene species Rh(H)(2)Cl(IPr)(IMes) (5a) was also observed but not isolated. A benzene solution of 5 under D-2 slowly generates the corresponding dideuteride. Reactions of the mono-carbenes (1/3, or 2/4) with CO in hexane afford the respective dicarbonyl complexes RhCl(CO)(2)(NHC) [NHC = IPr (6), IMes (7)], while CO reactions with the bis-carbene dihydrides give, respectively, the mono-carbonyl complex RhCl(CO)(IPr)(2) (8) and the known IMes analogue. All the complexes are characterized by elemental analysis, H-1 and C-13{H-1} NMR and IR spectroscopies and, in the case of 5, by X-ray crystallography. The catalytic activities of 5 and the previously reported Rh(H)(2)Cl(IMes)(2) for hydrogenation of COE and 1-octene (and isomerization of the latter) are shown to be poor.

The synthesis of 4 surprisingly requires the reaction to be carried out under a hydrogen atmosphere and occurs via the intermediate dihydride RhCl(H)(2)(IPr)(P-N) (3). Complexes 4-7 in benzene readily undergo irreversible oxidative addition of O-2 to form the corresponding Rh(III) peroxide complexes 9-12. For comparative purposes, RhCl(PPh3)(P-N) (8) was synthesized from RhCl(PPh3)(3), and this also added O-2 to form a peroxo complex (13). All of the complexes were generally characterized by elemental analysis and H-1, P-31{H-1}, and C-13{H-1} NMR and IR spectroscopies and, in the cases of 9, 10, and 13, by X-ray crystallography.},

This medium allows for trivial separation of the trans-stilbene product which precipitates after the reaction mixture is cooled. The bimetallic precursors are more active than predicted from the sum of the activities of complexes chosen to mimic their mono-metallic "half units," suggesting some degree of intermetallic cooperativity during the reaction. A non-linear dependence of initial rate on catalyst concentration implies, however, that the complexes do not remain intact, and may be involved in dissociative equilibria with non-dmapm containing monometallic components that are more active species for the Heck coupling. The complexes are slowly degraded by oxidation at a phosphorus centre. A general index for quantifying the degree of intermetallic cooperativity during a catalytic cycle is proposed and its utility and limitations are discussed.},
