Diazadithiafulvalenes as electron donor reagents

Journal of the Chemical Society, Perkin Transactions 1, 1999
Diazadithiafulvalenes act as excellent electron donors to arenediazonium salts. The diazadithiafulvalenium radical cations trap primary carbon radicals successfully. However, the diazadithiafulvalenium salts which form, undergo rapid ring fragmentation in contrast to their tetrathia counterparts.

Octabutoxyphthalocyanine, a new electron donor

J. Chem. Soc., Dalton Trans., 1988
The preparation of the 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine zinc complex (1) is described. The electron-donating groups influence the properties of the compound. The oxidation–reduction potentials studied by cyclic voltammetry in solution shift by ca.

Metallocenes, Strong Electron Donors

2003
For many years it was puzzling that metal atoms, which were not considered good Lewis acids, could form adducts with CO, considered to be a poor donor toward most Lewis acids. An example is the hexacarbonylchromium, Cr(CO)6. On the other hand, it was stressed that chromium, having 24 electrons, by accepting 6x2 electrons from 6 CO molecules, will fill ...

Dimeric Tetrathiafulvalenes: New electron donors

Advanced Materials, 1996
Organic conductors based on new classes of dimeric TTFs (e.g., see figure) are reviewed. The complexes have structures in some cases which are determined by inter‐TTF transannular interactions, leading to stretched, folded, and sandwich arrangements.

Tetraaminoethylenes as Strong Electron Donors

Angewandte Chemie International Edition in English, 1968
AbstractDepending on the nature of the electron acceptor and of the tetraaminoethylene (TAE), the electron pairs of the ethylenic double bond (A), of the nitrogen (B), or of the entire electronic system (C) of TAE react with the acceptor. Thus oxidizing agents convert TAE into the mono‐and dications TAE+ and TAE2+ by path (A); acids add on to the ...

Ionization Potentials of Electron Donors

Nature, 1959
RECENTLY, Briegleb and Czekalla1 have described a method of determining the ionization potentials (I p) of electron donors from the frequencies (ν) of the charge-transfer bands of the complexes of these donors with certain electron acceptors. This is based on a non-linear theoretical relationship between I p and ν.
