Preparation of cyclopropanone 2,2,2-trifluoroethoxy hemiacetals via oxyallyl cation
(ARKAT USA, Inc., 2024)
Hemiacetals of cyclopropanone can be isolated and stocked, contrary to their highly reactive parent ketone. However, they are not readily converted to cyclopropanone, which limits their use as its synthetic equivalents. ...
Titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides: a new method for the synthesis of gamma-butanolides
(Oxford : Pergamon-Elsevier Science Ltd, 2002)
A new method for the synthesis of gamma-butanolides is described. The titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords the corresponding butyrolactones in ...
New organoruthenium compounds with pyrido[2′,3′:5,6]pyrazino[2,3-f][1, 10]phenanthroline: synthesis, characterization, cytotoxicity, and investigation of mechanism of action
(Springer Link, 2019)
Three new ruthenium(II)-arene complexes with pyrido[2′,3′:5,6]pyrazino[2,3-f][1, 10]phenanthroline (ppf) of general formula: C1 ([(ƞ 6 -benzene)Ru(ppf)Cl]PF 6 , C2 ([(ƞ 6 -toluene)Ru(ppf)Cl]PF 6 ) and C3 ([(ƞ 6 ...
Half-sandwich ruthenium(II)-arene complexes: synthesis, spectroscopic studies, biological properties, and molecular modeling
(Taylor & Francis, 2019)
In search for antitumor metal-based drugs that would mitigate the severe side-effects of cisplatin, Ru(II) complexes are gaining increasing recent interest. In this work, we report on the synthesis, characterization (1H- ...
Strong in Vitro Cytotoxic Potential of New Ruthenium-Cymene Complexes
(American Chemical Society (ACS), 2015)
Two p-cymenerutheniumchlorido complexes with thiourea derivative of 7-chloroquinoline (C1) and pyridine-3-imidazole (C2) were synthesized starting from [(eta(6)-p-cymene)RuCl2](2) and corresponding ligands. The structures ...
Synthesis, structures and electronic properties of Co(III) complexes with 2-quinolinecarboxaldehyde thio- and selenosemicarbazone: A combined experimental and theoretical study
(Serbian Chemical Soc, Belgrade, 2017)
Cobalt(III) complexes derived from thio-and selenosemicarbazone ligands have been studied to elucidate the nature and consequences of S to Se substitution on their possible biological activity. Solid state structures of ...
Half-sandwich ruthenium(II)-arene complexes: synthesis, spectroscopic studies, biological properties, and molecular modeling
(Taylor & Francis, 2019)
In search for antitumor metal-based drugs that would mitigate the severe side-effects of cisplatin, Ru(II) complexes are gaining increasing recent interest. In this work, we report on the synthesis, characterization (1H- ...
Electrochemical, theoretical, and morphological studies of antioxidant fullerosteroids
(Springer Wien, Wien, 2014)
Four fullerosteroidal conjugates, previously confirmed to express two- to threefold better antioxidant activity in vitro than C-60, were subjected to additional studies, including electrochemical, theoretical, and morphological ...
Promising in vitro and in silico biological activity of tetradentate Schiff base copper(II) complexes with a propylenediamine bridge
(Royal Society of Chemistry, 2024)
The molecular structures of six neutral copper(II) complexes with propylenediamine bridges and different terminal groups have been reported and evaluated. Different antioxidant tests were performed on these complexes. ...
