C–N Bond Coupling Reactions of Ammonia with Acetone Promoted by Iridium and Rhodium Complexes: Experimental and DFT Studies

Treatment of acetone solutions of the known chlorido-bridged complexes [{M(μ-Cl)(cod)}2] (M = Ir, Rh; cod = 1,5-cyclooctadiene) under an ammonia atmosphere afforded the cationic complexes {M(cod)[κN,κN-NH2–C(CH3)2–CH2–C(CH3)=NH]}Cl [M = Ir (3), Rh (4)]. The molecular structures of 3 and 4 showed the formation of six-membered metallacycles due to the presence of a 4-imino-2-methylpentan-2-amine-κN,κN-chelated ligand. Alternatively, the cations [M(cod)(NCCH3)2]BF4(M = Ir, Rh) reacted with gaseous ammonia at atmospheric pressure affording bis(ammine) complexes [M(cod)(NH3)2]BF4[M = Ir (5), Rh (6)], which were found to react with acetone, forming cations [M(cod)(κN,κN-NH2–C(CH3)2–CH2–C(CH3)=NH)]BF4[M = Ir (7), Rh (8)]. DFT studies reveal that the transformation of 6 into 8 is mediated by NH3molecules acting as an external base. The reaction is triggered by deprotonation of an ammonia ligand forming a amido–metal intermediate, which further transforms into an acetimino ligand through aldol condensation. The terminal methyl group of one acetimino ligand is deprotonated by NH3yielding an enamine ligand, which can react with the imine ligand through concerted nucleophilic addition to afford the metallacycle, which is stabilized by protonation.

A Silica-Supported Rhodium Hydroformylarion Catalyst: Evidebce for Dinuclear Elimination

Treatment of 3-(4-chlorophenoxy)-1,2-propanediol with MsCl and subsequently with NaPPh2 gave the diphosphine 2, which could be converted to the silylated phosphines 3 and 4 and attached to silica gel.It was determined experimentally that these ligands are distributed randomly on the silica surface.The synthesis of (P2)RhNBD+BF4- (14) and (P2)RhC3H5 (16) (P2 = 4) is described.Both 14 and 16 are precursors of monohydride catalysts for hydroformylation of styrene under mild conditions.When the silica-supported analogue of 14 was used as a catalyst precursor, the rate per rhodium was found to depend on the distribution of the catalyst on the silica surface.The role of dinuclear reductive elimination is discussed.
