Reactions of (C5Me5)2Sm(THF)2 with 1 equiv K(ER) in THF gave high yields the Sm(II) complexes [(C5Me5)Sm(THF)m(ER)(μ-C5Me5)K(THF)n]∞ (m = 0 or 1; n 2; ER OC6H2tBu2-2,6-Me-4 (1a), OC6H3iPr2-2,6 (1b), SC6H2iPr3-2,4,6 (1c), NHC6H2tBu3-2,4,6 (1d), N(SiMe3)2 (1e)), which "(C5Me5)K(THF)n" unit acts as a neutral coordination ligand bonding to center "C5Me5" part. The similar reaction (C5Me5)2Yb(THF)2 KN(SiMe3)2 yielded corresponding Yb(II) complex [(C5Me5)Yb(N(SiMe3)2)(μ-C5Me5)K(THF)2]∞ (1f) 90%...
Role model: The photochemical and electrochemical properties of a polypyridylruthenium complex with an NAD+/NADH (NAD+=nicotinamide adenine dinucleotide) model ligand, [Ru(bpy)2(pbn)]2+ ([1]2+; bpy=2,2′-bipyridine, pbn=2-(2-pyridyl)benzo[b]-1,5-naphthyridine), were investigated. When solutions containing [1]2+ triethylamine are irradiated visible light, [(1)HH]2+ is produced cleanly (see scheme). Supporting information for this article available on the WWW under...
Electrochemical reduction of [Ru(pbn)(bpy)2]2+ (1, pbn=2-(2-pyridyl)benzo[b]-1,5-naphthyridine, bpy=2,2′-bipyridine) in an acidic solvent gives [Ru(pbnH2)(bpy)2]2+ (2), which releases the hydrogen as "hydride" (see scheme). This catalytic system reduces substrates (for example, acetone) with two electrons and protons from water, thus operates a similar way to NAD+/NADH redox couple.

The catalytic organic-hydride transfer to CO2 was first achieved through the photoinduced two-electron reduction of [Ru(bpy)2 (pbn)]2+ /[Ru(bpy)2 (pbnHH)]2+ (bpy=2,2'-bipyridine, pbn=2-(pyridin-2-yl)benzo[b]-1,5-naphthyridine, and pbnHH=2-(pyridin-2-yl)-5,10-dihydrobenzo[b]-1,5-naphthyridine) redox couple in presence 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole (BIH). active species for hydride carbon dioxide giving formate is [Ru(bpy)(bpy⋅- )(pbnHH)]+ formed by one-electron with BI⋅.

Abstract It is shown that industrially available 2,3-dichloro-1,3-butadiene a useful starting material for the synthesis of 2,3-diaryl-1,3-butadienes. Ni(II)-catalyzed cross-coupling reaction with ArMgBr (Ar = 2-thienyl, phenyl, 4-dodecyloxyphenyl, and 4-fluorophenyl) gives corresponding 2,3-diaryl-1,3-butadienes in good yields.

A pseudorotaxane with different or mixed counter anions undergoes thermal phase transition, which is related to the interaction between anion and macrocyclic component.
Abstract Bis( N ‐butoxycarbonyl indroquinoxaline) derivatives with various junctures and arylene units were prepared. Optical electrochemical properties dependent not only on the juncture system but also introduced unit at two indroquinoxalines. Both heating addition of trifluoroacetic acid to compounds afforded cleavage (Boc) form bis(N−H type derivatives. Conversion Boc caused optical change. These suggest that indroquinoxaline are expected be changed by chemical modification.
