Synthesis and (spectro)electrochemistry of mixedvalent diferrocenyl–dihydrothiopyran derivatives
(Royal Society of Chemistry, 2015-02-20)
Three novel diferrocenyl complexes were prepared and characterised. 2,2-Diferrocenyl-4,5-dimethyl-
3,6-dihydro-2H-thiopyran (1, sulphide) was accessible by the hetero-Diels–Alder reaction of diferrocenyl
thioketone with ...
On the strong difference in reactivity of acyclic and cyclic diazodiketones with thioketones: experimental results and quantum-chemical interpretation
(Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2015-04-20)
The 1,3-dipolar cycloaddition of acyclic 2-diazo-1,3-dicarbonyl compounds (DDC) and thioketones preferably occurs with Z,Econformers
and leads to the formation of transient thiocarbonyl ylides in two stages. The ...

Hetero-Diels–Alder reactions of hetaryl and aryl thioketones with acetylenic dienophiles
(Beilstein Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2015-04-28)
Selected hetaryl and aryl thioketones react with acetylenecarboxylates under thermal conditions in the presence of LiClO4 or, alternatively,
under high-pressure conditions (5 kbar) at room temperature yielding thiopyran ...
Why 1,2‑quinone derivatives are more stable than their 2,3‑analogues?
(Springer Berlin Heidelberg, 2015-02-25)
In this work, we have studied the relative stability
of 1,2- and 2,3-quinones. While 1,2-quinones have
a closed-shell singlet ground state, the ground state for
the studied 2,3-isomers is open-shell singlet, except ...
The Influence of Protonation on the Electroreduction of Bi (III) Ions in Chlorates (VII) Solutions of Different Water Activity
(Springer, 2015-02-24)
We examined the electroreduction of Bi (III) ions in
chlorate (VII) solutions under varied protonation conditions of
the depolariser using voltammetric and impedance methods.
The results of the kinetic parameter correlation ...
Phase Behavior and Heat Capacity of {DPnP + Water} Mixtures at the Temperature Range of 273.15–338.15 K
(Hindawi Publishing Corporation, 2015)
The differential scanning calorimetry method (DSC) was used to examine the miscibility in the {dipropylene glycol propyl
ether (DPnP) + water} system.
Effects of Constant Magnetic Field on Electrodeposition of Co-W-Cu Alloy
(Electrochemical Science Group, 2015-03-23)
The paper presents a study of the effect of constant magnetic field (CMF) on the basic processes of
Co-W-Cu alloys electrodeposition. The alloys electrodeposited in the presence of CMF were more
homogeneous and smooth ...
Effect of base–acid properties of the mixtures of water with methanol on the solution enthalpy of selected cyclic ethers in this mixture at 298.15 K
(Akadémiai Kiadó, 2015-03-27)
The enthalpies of solution of cyclic ethers: 1,4-
dioxane, 12-crown-4 and 18-crown-6 in the mixture of
water and methanol have been measured within the whole
mole fraction range at T = 298.15 K. Based on the obtained
data, ...
Anticancer and Antibacterial Activity Studies of Gold(I)-Alkynyl Chromones
(MDPI, 2015)
Three gold(I) complexes of alkynyl chromones were synthesized and characterized. The
single-crystal X-ray structure analysis of a dinuclear compound and of a flavone derivative exhibit
a typical d10 gold(I)-alkynyl linear ...
