Electronic, Magnetic and Local structure of Some Selected Strongly Correlated Systems
According to independent electron band structure theories, transition metal oxides (TMOs) with partially filled 3d valence band are predicted to be metallic in nature. Though in reality, most of them are insulators. Mott ... -
Enantioselective Annulation Reactions: From Fischer Indolization to de novo Arene Construction
In summary, we have developed the first decarboxylative [4+2]-annulation of ethynyl benzoxazinanones with azlactones for the enantioselective synthesis of cyclic α-quaternary α-acylaminoamides.25 This direct and modular ... -
