Organic Synthesis and Wittig Olefination
- Ethyltriphenylphosphonium bromide is used as a phosphonium-salt precursor that is converted into a phosphorus ylide for Wittig-type carbon–carbon bond construction. Ethyltriphenylphosphonium bromide is selected when a controlled olefination step is needed to transform aldehydes or ketones into targeted alkene intermediates under anhydrous conditions.
- Ethyltriphenylphosphonium bromide is applied in olefination workflows where base selection and temperature control are used to tune reactivity and manage selectivity.
