Evolution of neutral organic super-electron-donors and their applications.
In recent times, metal-free chemistry has received significant attention due to its inherent qualities and its potential savings in the costs of (i) reagents and (ii) environmental treatments of residues. In this context, recently developed neutral organic electron-donors have shown an ability to perform challenging reductions that are traditionally the preserve of reactive metals and metal-bas...
متن کاملDiscovery and Development of Organic Super-Electron-Donors
Based on simple ideas of electron-rich alkenes, exemplified by tetrakis(dimethylamino)ethene, TDAE, and on additional driving force associated with aromatization, families of very powerful neutral organic super-electron-donors (SEDs) have been developed. In the ground state, they carry out metal-free reductions of a range of functional groups. Iodoarenes are reduced either to aryl radicals or, ...
متن کاملImpact of Organic Carbon Electron Donors on Microbial Community Development under Iron- and Sulfate-Reducing Conditions
Although iron- and sulfate-reducing bacteria in subsurface environments have crucial roles in biogeochemical cycling of C, Fe, and S, how specific electron donors impact the compositional structure and activity of native iron- and/or sulfate-reducing communities is largely unknown. To understand this better, we created bicarbonate-buffered batch systems in duplicate with three different electro...
متن کاملSolution-processed new porphyrin-based small molecules as electron donors for highly efficient organic photovoltaics.
A series of unsymmetrical π-conjugated small molecules have been constructed from meso-alkyl substituted porphyrins as the central unit and 3-ethylrhodanine as the terminal group. Using PC71BM as an acceptor, and these small molecules as electron donors in solution-processed bulk-heterojunction solar cells, a high power conversion efficiency of 6.49% has been achieved.
متن کاملDistonic Radical Anions Generated via Single Electron Transfer and Their Potenial In Organic Synthesis
Herein, recent developments in the production and reactivity of distonic radical anions are reviewed. Known and potential reactions utilizing both the radical and anion centers are highlighted. While work has revealed new distonic radical anion species, limited effort has been to apply them to complex molecule synthesis. Through the development of new photoinduced electron transfer reagents, di...
