In the title compound, C(30)H(20)N(2), the anthracene ring system is approximately planar [maximum deviation = 0.035 (2) Å] and is nearly perpendicular to the central pyridine ring, making a dihedral angle of 75.73 (7)°. The terminal pyridine ring and the phenyl ring are oriented at dihedral angles of 8.11 (10) and 13.22 (10)°, respectively, to the central pyridine ring.

Direct arylation reactions of pyridine N-oxides occur in excellent yield with complete selectivity for the 2-position with a wide range of aryl bromides. This reactivity permits the use of inexpensive, commercially available, and bench-stable pyridine N-oxides as replacements for problematic 2-metallapyridines in palladium-catalyzed cross-coupling reactions.

The asymmetric unit of the title compound [Mn(NCS)(2)(C(9)H(13)N)(4)] consists of one Mn(II) cation located on a center of inversion, one thio-cyanato anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.60:0.40 ratio. The Mn(II) cation is coordinate...

The asymmetric unit of the title compound, [Cd(NCS)(2)(C(9)H(13)N)(4)], consists of one Cd(II) cation located on a centre of inversion, one thio-cyanate anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.25:0.75 ratio and was refined using a split ...

The title compound, C17H14Cl4N5OP3, is a spiro-phosphazene derivative with bulky naphthalene and pyridine rings. The phosphazene and the six-membered N/O rings are in flattened-boat and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 18.06 (8)°. In the crystal, weak π-π stacking between the pyridine rings and betwee...


 ABSTRACT. A novel series of mononuclear complexes the type, [M(L)(H2O)2] [M = Co(II) (1), Ni(II) (2), Zn(II) (3), Cd(II) (4), L dipicolinate), has been investigated using various techniques, including elemental analyses, FT-IR, 1H- and 13C NMR spectroscopy, powder XRD thermogravimetric analysis. The results indicate that coordination dipicolinic acid to metal ions involves two carboxylat...

Abstract New spiro[cyclohexane-1,2'-thiazolo[4,5- b ]pyridine derivatives ( 3 – 23 ) were investigated. Then there is in vitro antimicrobial potency against possible organisms Staphylococcus aurous ATCC-47,077, Bacillus cereus ATCC-12228, Escherichia coli ATCC-25922, Salmonella typhi ATCC-15566, and Candida albicans ATCC-10231 tested utilizing commercially available antibiotics ampicillin as a ...

The first paper of this series (1) reported the results of tests of the carcinogenic activity of cer tam analogs of p-dimethylaminoazobenzene (DAB) in which a pyridine ring or a thiazole ring replaced one of the benzene rings of DAB. Due to the presence of the hetero atom or atoms, position isomers are possible in the heterocyclic analogs, and some of these isomers were synthesized and tested. ...

The thermolytic coupling of Ph(2)CN(2) and (t-Bu)(Ph)CN(2) with doubly cyclomanganated 2,5-diphenylpyrazine and 4,6-diphenylpyrimidine afforded substantial amounts of new triple decker compounds of either C(i) and C(2) symmetry respectively containing, in both series, two eta(3)-bonded Mn(CO)(3) fragments which intervene as scaffolds sustaining the helical non-conjugated triaryl backbone. The m...

Dawson et al. (1) have shown that the pyridine ring of nicotinic acid is utilized to form the pyridine ring of nicotine in sterile cultures of tobacco root. Since studies with animals and some microorganisms have demonstrated that tryptophan is converted to nicotinic acid (2)) tryptophan might reasonably be expected to yield the pyridine ring of nicotine. However, experiments have shown conclus...
