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. ...
The role of DFT in characterization of coordination compounds: opportunities and challenges
(Viena, Austria : Institute of Applied Synthetic Chemistry, TU WienChemIT e.U., 2023)
In the last two decades, considerable theoretical efforts have been made to develop suitable methods for predicting and rationalizing the complicated electronic structure of TM compounds. However, the matter remains open ...
Relativistic DFT calculation and their effect on the accuracy of results
(Kragujevac, Serbia : Institute for Information Technologies, University of Kragujevac, 2023)
This study explores the significance of density functional theory (DFT) calculations with relativistic effects for two ethylenediaminetetraacetate (edta) type complexes: trans(O5)-[M(eddadp)]- (M = Rh3+, Co3+). Relativistic ...
