If a molecule is electron-deficient, it becomes electron-hungry, or electrophilic, and can now be looked upon as an oxidizing agent.

This activation produces what is now known as superelectrophiles, that is, electrophiles of doubly electron-deficient (dipositive) nature whose reactivity significantly exceeds that of their parents.

Ahead of the Scapa Flow, two capacitors 'worth of free electrons combined with those from the vaporized netting fibers, the whole mass of them rushing at Van de Graaff speeds toward the most electron-deficient object anywhere around them —

Organic semiconductor lasers detect explosive vapors because of a chemical interaction between the vapor and the semiconductor in which electrons are transferred from the semiconductor to the electron-deficient vapor molecules.
