The Importance Of Electron Interactions
In this chapter a review of earlier electron donors and the different electron transfer will be developed.
1.1 Organic electron donors
Since the earlier 1970s tetrathiafulvalene (TTF) organic compound has aroused great interest. TTF is an organic compound, which has attached four sulphur atoms to the central double-bond, as it can observe in the scheme 1. This compound is capable of donating …show more content…
Then compound 2 can again be oxidised to give compound 3, as it can see in the scheme 1. Moreover, these processes are reversible; therefore TTF2+ compound could reduce to TTF and TTF. Moreover, it is important to know that the reduction potentials are different for the compound 2 and the compound 3. The reduction potential of the compound 2 is lower than the reduction potential of the compound 3. The reduction potential of the compound 2, which has 2 resonance forms (4 and 5, shown in scheme 2), is lower than the reduction potential of the compound 3, therefore the loss of the first electron is more …show more content…
This property has been studied in different fields such us in organic conductors, solar cells and photovoltaic cells.
1.2 Electron transfer
Organic synthesis is based on electron-transfer chemical reactions. Some metals, for instance are capable of donating a single electron; moreover, a single electron can be donated due to the electrochemical processes and photochemical processes. In the following section different kind of electron transfer reagents will be developed.
1.2.1 Metals as electron transfers
126.96.36.199 Transition metals Some transition metals show electron transfer chemistry. Moreover, these metals are used in synthesis reaction. Some of them will be presented bellow.
Some iron salts, such as FeSO4 are reducing agents, while another iron salts, for instance FeCl3 are mild oxidising agents.
• The menisci reaction. It is an organic reaction. It consists of radical substitution to a heteroaromatic base, which introduces an alkyl group. The aromatic compound is usually electron deficient and with N-aromatic compounds the nitrogen is protonated. 4 5 6
