Ma, Wenpeng published the artcileRuthenium-Catalyzed Enantioselective Hydrogenation of 1,8-Naphthyridine Derivatives, Name: 2,7-Dimethyl-1,8-naphthyridine, the publication is Organic Letters (2016), 18(11), 2730-2733, database is CAplus and MEDLINE.

The first asym. hydrogenation of 2,7-disubstituted 1,8-naphthyridines catalyzed by chiral cationic ruthenium diamine complexes has been developed. A wide range of 1,8-naphthyridine derivatives were effectively hydrogenated to give 1,2,3,4-tetrahydro-1,8-naphthyridines with up to 99% ee and full conversions. The method provides a practical and facile approach to the preparation of valuable chiral heterocyclic building blocks and useful motifs for a new kind of P,N-ligand.

The complete mol. of 2,7-bis(trichloromethyl)-1,8-naphthyridine, C₁₀H₄Cl₆N₂, is generated by crystallog. 2-fold symmetry, with 2 C atoms lying on the rotation axis; the 1,8-naphthyridine ring is almost planar with an root-mean-square deviation of 0.0002 Å. In the crystal structure, the mols. are stacked in an antiparallel manner along [001]. Short Cl···Cl [3.3502(4)] and Cl···N [3.2004(11)-3.2220(10) Å] contacts are observed in the crystal structure, as are π-π antistacking interactions. Crystallog. data are given.

Gu, Yang published the artcileWell-defined, shelf-stable (NHC)Ag(CF₂H) complexes for difluoromethylation, Related Products of naphthyridine, the publication is Organometallics (2015), 34(12), 3065-3071, database is CAplus.

The preparation of the thermally stable, well-defined 1,3-bis(2,6-diisopropylphenyl)imidazol(idin)ylidene NHC-ligated difluoromethylated silver complexes [(NHC)AgCF₂H] (1a, NHC = SIPr, 1b, NHC = IPr) is described. The complexes were fully characterized, and the structural assignments were unambiguously further confirmed by single-crystal x-ray diffraction. Reactions of [(SIPr)Ag(CF₂H)] with a variety of activated electrophiles such as diaryliodonium salts, vinyl(aryl)iodonium salts, and acid chlorides in the presence or absence of CuI occurred smoothly at room temperature to generate difluoromethylated arene and alkene compounds in good to excellent yields; whereas aryldiazonium salts ArN₂⁺X^– typically gave aryl difluoromethyl diazenes ArN:NCF₂H, even without copper catalyst.

Hendricker, David G. published the artcileComplexes of 1,8-naphthyridines. III. Transition metal-perchlorate complexes of 2,7-dimethyl-1,8-naphthyridine, Product Details of C10H10N2, the publication is Inorganic Chemistry (1970), 9(2), 273-7, database is CAplus.

A number of transition metal-perchlorate complexes of the type ML3(ClO4)2 (M = Fe, Cu, Ni, Co, Zn, and Cd), HgL2(ClO4)2, and AgL2Cl o4, where L = 2,7-dimethyl-1,8-naphthyridine, have been synthesized. Elemental analyses, molar conductances, magnetic moments, and IR and electronic spectral data have been applied to the characterization of the compounds The resulting ligand field parameters place the present ligand nearer pyridine than 1,10-phenanthroline and 2,2-bipyridine in the spectrochem. series. Since the latter 2 are very similar in basicity and synergic bonding to L, the resulting weak ligand field property is attributed to strain produced in the formation of a 4-member chelate ring system.
