Preparation, properties, and structures of pentanuclear [{Ni2l}2(μ-csalen)M]2+ complexes (l = macrocyclic N6S2 donor ligand)

The dinuclear nickel complex [Ni2L(μ-Cl)]+ (1), where L2- is a 24-membered macrocyclic N6S2 ligand, reacts readily with 3-form-yl-4-hydroxy-benzoic acid (Hfhba) to form the carboxylato-bridged complex [Ni2L(μ-fhba)]+ (2). Complex 2 undergoes a condensation reaction with ethylene diamine to produce a tetranuclear complex [{Ni2L}2(μ-H2csalen)]2+ + (3), in which two dinuclear {Ni2L} units are bridged via the deprotonated carboxylate functions of the csalen ligand N,N′-bis(4-carboxysalicylidene)-1,2-diaminoethane. The same compound can also be prepared directly from 1 and H2csalen. The complexation of 3 with NiCl2?6H2O, Cu(OAc)2?H2O or Pd(OAc)2 provides pentanuclear complexes of the type [{Ni2L}2(μ-csalen)M]2+ [M = Ni (4a), Cu (4b), Pd (4c)]. All complexes were isolated as perchlorate salts and studied by ESI-MS, infrared, and UV/Vis spectroscopy. The tetraphenylborate salt of 4c was also characterized by X-ray crystallography. The [(csalen)M] complex units act in all cases as quadridentate bridging ligands linking two bioctahedral {Ni2L} units via μ-1,3-bridging carboxylate functions. The palladium complex 4c was found to catalyze Heck-coupling reactions of various iodobenzenes with methyl acrylate and styrene.

A Bidentate Ru(II)-NC Complex as a Catalyst for Semihydrogenation of Alkynes to (E)-Alkenes with Ethanol

Four Ru(II)-NC complexes were tested as catalysts for semihydrogenation of internal alkynes to (E)-alkenes with ethanol, and the complex {(C5H4N)(C6H4)}RuCl(CO)(PPh3)2 (1a) showed the highest activity. The reactions proceeded well with 1 mol % catalyst loading and 0.1 equiv of t-BuONa at 110 °C for 1 h, and 32 alkenes were synthesized with excellent E:Z selectivity. This is the first ruthenium-catalyzed semihydrogenation of internal alkynes to (E)-alkenes using ethanol as the hydrogen donor.

Highly Chemo- and Stereoselective Transfer Semihydrogenation of Alkynes Catalyzed by a Stable, Well-Defined Manganese(II) Complex

Herein we report unprecedented manganese-catalyzed semihydrogenation of internal alkynes to (Z)-alkenes using ammonia borane as a hydrogen donor. The reaction is catalyzed by a pincer complex of the earth-abundant manganese(II) salt in the absence of any
