Synthesis of novel arylthio derivatives of mucochloric acid

Stable reaction products of mucochloric acid with aromatic and heterocyclic thiols were synthesized and characterized. Under basic conditions the reactions proceeded with the substitution of the chlorine atom(s) by arylthiogroup(s), while in an acidic medium the hydroxy group at C5 was substituted. Different types of new sulfur-containing products of di- and trisubstitution on the basis of mucochloric acid were obtained. In one case a new acyclic product - di-p-tolyl-2,3-bis-(p-tolylthio)butanedithioate - was isolated. The structure of all synthesized compounds was confirmed by IR, 1H, and 13C NMR spectroscopy; three compounds were characterized by single crystal X-ray diffraction.

Тне intranatal causes of grave condition at premature newborns

In this article we present statistic analysis of delivery tactic in premature labors. The newborns of those mothers who took the tocolitical therapy and prevention of RDS were needed in artificial pulmonary ventilation accordingly in 3,3-5,0 and twice times rarer

A Dyad as Photocatalyst for Light-Driven Sulfide Oxygenation with Water As the Unique Oxygen Atom Source

International audienceWith the objective to convert light energy into chemical oxidation energy, a ruthenium-based dyad constituted of the assembly of a photosensitizer and a catalytic fragment was synthesized. Upon irradiation with blue LEDs, and in the presence of an electron acceptor, the complex is able to catalyze selective sulfide oxygenation involving an oxygen atom transfer from water to the substrate. Electrochemical and photophysical studies highlighted a proton-coupled electron transfer (PCET) to access to a high valent oxidant Ru(IV) oxo species
