Deuteration of Six-Membered N-Heteroarenes: Chemistry and Applications. [PDF]

open access: yesChemistry
Deuterated six‐membered N‐Heteroarenes (6NHetAr) are finding utility in an increasing repertoire of applications. Our paper comprehensively reviews synthetic approaches that have been reported for the deuteration of 6NHetAr and their fused counterparts while providing an overview of established and emerging applications for these materials.

Photoinduced, Chemoselective γ-Alkylation of 2-Silyloxyfurans With α-Bromoketones: A Rapid Entry to Chiral ε-Keto-γ-Butenolides. [PDF]

open access: yesChemistry
A photoinduced, regio‐ and chemoselective γ‐alkylation of 2‐silyloxyfurans with a‐bromoketones was achieved by exploiting a photoredox catalytic process promoted by blue light. This approach provides practical and efficient access to chiral, ε‐ketobutenolides, in one step and high yields.

Dye-sensitized Photooxygenation of furanosyl Furans; Synthesis of a new Pyridazine C-Nucleoside [PDF]

open access: yes, 2005
The dye-sensitized photooxygenation of furanosyl furans easily affords C- or O-glycosides with cis-R,-unsaturated 1,4-dioxo aglycones. The reaction, performed on a ribofuranosyl furan, provides a useful new entry to a novel pyridazine C-nucleoside that ...

Comparative Inhibition Study of New Synthesised Pyridazine Derivatives Towards Mild Steel Corrosion in Hydrochloric Acid. Part-II: Thermodynamic Proprieties

open access: yesInternational Journal of Electrochemical Science, 2012
The corrosion rates in the presence of new synthesised pyridazine derivatives (P1, P2, P3 and P4) as a steel corrosion inhibitors in 1 M hydrochloric acid, were measured by the weight loss method, in the range of temperatures from 303 to 353 K.

Immobilization of Fe(III) complexes of pyridazine derivatives prepared from biosorbents supported on zeolites [PDF]

open access: yes, 2008
Immobilization of Fe(III) complexes of pyridazine derivatives was achieved in NaY zeolite, loaded with iron through the action of a robust biosorption mediator consisting of a bacterial biofilm, Arthrobacter viscosus, supported on the zeolite.
