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 an electron due to sulphur atoms donate electron density to its π system. It is …show more content…
This system has caused much attention over the last four decades, because of its electron donor properties. 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
1.2.1.2 Transition metals Some transition metals show electron transfer chemistry. Moreover, these metals are used in synthesis reaction. Some of them will be presented
