Journal ArticleDOI
Spectral and structural studies of iron(III), cobalt(II,III) and nickel(II) complexes of 2-pyridineformamide N(4)-methylthiosemicarbazone
Douglas X. West,John K. Swearingen,Jesús Valdés-Martínez,Simón Hernández-Ortega,Ayman K. El-Sawaf,Frank van Meurs,Alfonso Castiñeiras,Isabel Garcı́a,Elena Bermejo +8 more
TL;DR: In this paper, the reduction of 2-cyanopyridine by sodium in dry methanol in the presence of N(4)-methylthiosemicarbazide produces 2-pyridineformamide, HAm4M. Coordination is via the pyridyl nitrogen, imine nitrogen and thione or thiolato sulfur when coordinating as the neutral and anionic ligand, respectively.
Journal ArticleDOI
Structural studies of three isomeric forms of heterocyclic N(4)-substituted thiosemicarbazones and two nickel(II) complexes
Douglas X. West,Gordon A. Bain,Ray J. Butcher,Jerry P. Jasinski,Yu Li,Roman Y. Pozdniakiv,Jesús Valdés-Martínez,Rubén A. Toscano,Simón Hernández-Ortega +8 more
TL;DR: In this article, three structural forms have been isolated among four 2-formyl- and 2-acetylpyridine N(4)-substituted thiosemicarbazones reported.
Journal ArticleDOI
Alkyl- and arylthiolation of aryl halides catalyzed by fluorinated bis-imino-nickel NNN pincer complexes [NiCl2{C5H3N-2,6-(CHNArf)2}]
TL;DR: In this paper, the synthesis of bisimino nickel(II) NNN pincer complexes of the type [NiCl 2 {C 5 H 3 N-2,6-(CHNAr f ) 2 }] has been achieved and their reactivity in alkyl and arylthiolation reactions of halobenzenes examined.
Journal ArticleDOI
Naphthoquinone spiroketal with allelochemical activity from the newly discovered endophytic fungus Edenia gomezpompae.
Martha L. Macías-Rubalcava,Blanca E. Hernández-Bautista,Manuel Jiménez-Estrada,María C. González,Anthony E. Glenn,Richard T. Hanlin,Simón Hernández-Ortega,Aurora Saucedo-García,Jordi M. Muria-González,Ana Luisa Anaya +9 more
TL;DR: This is the first report of allelochemicals with antifungal activity from the newly discovered endophytic fungus E. gomezpompae, and the acetylated derivatives of preussomerin EG1, 1a and 1b exhibited significant bioactivity against all microorganisms tested with the exception of Alternaria solani.
Journal ArticleDOI
Copper(II) and nickel(II) complexes of 2,3-butanedione bis(N(3)-substituted thiosemicarbazones)
Douglas X. West,Janeice S. Ives,Gordon A. Bain,Anthony E. Liberta,Jesús Valdés-Martínez,Klaus H. Ebert,Simón Hernández-Ortega +6 more
TL;DR: In this paper, the four thiosemicarbazones have been characterized by their melting points, as well as IR, electronic and NMR (1H, 13C) spectra.
