Polymer with tetrazolic pendant groups. Interaction between the heterocyclic groups and heavy metals
(Research Trends, 2013-03)
The interaction between a polymer with tetrazolic pendant groups, and heavy metals (Pb(II) or Cd(II)) was studied. The product resulting from these interactions was characterized by Fourier transform infrared spectroscopy, ...
Heterocyclic N-oxides -A promising class of agents against tuberculosis, malaria and neglected tropical diseases
(2018-01-01)
Heterocyclic N-oxides have emerged as promising agents against a number of diseases and disorders, especially infectious diseases. This review analyzes the emergence and development of this scaffold in the medicinal ...

Photochemistry of N-(selenoalkyl)-phthalimides. Formation of N, Se-heterocyclic systems
(Royal Society of Chemistry, 2015-04)
A variety of N-(selenomethyl)alkyl-phthalimides (alkyl = -(CH2)n-; n = 2-5, 1a, b, d, e) and N-(selenobenzyl)propyl phthalimide (1c) were synthesized and their photochemistry was studied at λ = 300 nm. Steady-state photolysis ...
Water-soluble N-heterocyclic carbene platinum(0) complexes: Recyclable catalysts for the hydrosilylation of alkynes in water at room temperature
(American Chemical Society, 2012-04)
The synthesis and characterization of new water-soluble platinum(0) complexes bearing sulfonated N-heterocyclic carbene (NHC) and divinyltetramethylsiloxane (dvtms) ligands are described. These complexes, of the general ...
Gold-Catalyzed Cycloisomerization of Alkyne-Containing Amino Acids: Controlled Tuning of C–N vs. C–O Reactivity
(Wiley VCH Verlag, 2016-06)
Versatile alkyne-containing amino acids were used as ambident precursors in the divergent synthesis of alkylidenelactones and 1-pyrrolines. Two gold-catalyzed protocols were applied for selective intramolecular O- and ...
Host hydrated barium phenylphosphonate/guest heterocyclic amine intercalation energetics by calorimetric titration

1π → 1π* ultraviolet absorption bands and electronic charge transfers in singlet excited states of sulfur aromatic heterocycles
(2005)
Indoline-2-thione (BC), benzimidazole-2-thione (BN), benzoxazole-2-thione (BO), and benzothiazole-2-thione (BS) define an interesting series of aromatic compounds containing a NCS synthonic unit in a heterocyclic ring of ...
Regioselective N-Functionalization of Tautomerizable Heterocycles through Methyl Trifluoromethanesulfonate-Catalyzed Substitution of Alcohols and Alkyl Group Migrations
(2022-02-15)
A catalytic synthetic strategy has been developed combining two protocols, such as, direct nucleophilic substitution of alcohols followed by X- to N- alkyl group migration (X=O, S) to access N-functionalized benzoxazolones, ...
