Alkenes are molecules organized around a carbon double bond. When the four peripheral atoms are hydrogen, this simplest alkene is ethylene. Such carbon based molecules are highly useful in pharmacology.
The production of alkenes is difficult by subtraction. Wittig's merit is to have obtained them in an organic synthesis. The combined presence of an aldehyde and a triphenylphosphine oxide creates the desired double bond of carbon by breaking the carbon-oxygen double bond of the aldehyde. Wikimedia provides the formula.
