- Learning How to Fine-Tune Diradical Properties by Structure
From this molecular blueprint for producing stable diradicals, the Haley lab has investigated how to fine tune diradical properties via structural changes in two key positions: (1) the length of the acene core and (2) thoughtful exchange of the outer arenes
- III. Generation of Carbon-Centered Radicals - Chemistry LibreTexts
Carbon-centered radicals often are generated by atom-transfer reactions The transfer usually is of a halogen atom, but hydrogen-atom transfer also can take place Absolute rate constants for producing carbon-centered radicals by reaction of halogenated compounds with Bu 3 Sn· are found in Table 1
- New Class of Carbon-Centered Diradicals Discovered
Quantum chemical calculations were performed to better understand the bonding situation, and the researchers found evidence for the presence of a triplet carbon atom in its ground state that accepts the lone pair from Ph 3 P and has two unpaired electrons, i e , the adduct has a diradical character
- Theoretical and experimental evidences for the formation of carbonate . . .
Experimental tests evidence that it is possible to form the carbonate anion radical in the atmosphere According to the simulations, the CO3- • radical reacts preferentially with electron-rich molecules such as H2S
- A Singlet-Diradical Co(III)-Dimer as a Nonvolatile Resistive Switching . . .
Herein we report a ligand-centered redox-controlled strategy for the synthesis of an unusual binuclear diradical cobalt (III) complex, [Co2III (L•3–)2] (1), featuring two three-electron reduced trian
- Radicals, Radical ion, Diradical and Diradicaloid Based on Silicon
Two electrons occupy two separate orbitals in both ground state triplet diradical and singlet diradical For example, molecular oxygen (O2) has a triplet ground state since two electrons occupy a double degenerated π*-orbital (↑↑)
- A Singlet-Diradical Co (III)-Dimer as a Nonvolatile Resistive . . . - PubMed
Herein we report a ligand-centered redox-controlled strategy for the synthesis of an unusual binuclear diradical cobalt (III) complex, [Co 2III (L •3-) 2] (1), featuring two three-electron reduced trianionic monoradical 2,9-bis (phenyldiazo)-1,10-phenanthroline ligands (L•3-) and two intermediate-spin cobalt (III) centers having a Co-Co bond
- Orbital Nature of Carboionic Monoradicals Made from Diradicals
For the study of small-medium diradical character in molecular hydrocarbons, molecular orbital theory based on unrestricted DFT becomes very suitable since electron correlation and spin polarization can be easily considered
