electrophile

electrophile

Atom or molecule that in a chemical reaction seeks an atom or molecule containing an electron pair available for bonding or the negative end of a polar molecule (see covalent bond; electric dipole). In the Lewis electron theory (see acid-base theory) advanced by the U.S. chemist Gilbert Lewis (1875–1946) in 1923, electrophiles are by definition Lewis acids. Examples include the hydronium ion (H3O+), boron trifluoride (BF3), and the halogens fluorine, chlorine, bromine, and iodine in molecular form. See also acid; nucleophile.


electrophile [i′lek·trō‚fīl]
(physical chemistry)
An electron-deficient ion or molecule that takes part in an electrophilic process.

It has been speculated (2) that the co-catalyst stabilizes and activates the colloid formed between the Karstedt's catalyst and PDMS by withdrawing electrons, therefore, increasing the electrophilicity of the Karstedt's catalyst.
