Wittig Reagents

We now offer a broad range of Wittig Reagents. Wittig Reagents are triphenyl phosphonium ylides and derivatives used to convert aldehydes and ketones into alkenes. The Wittig reaction is popular in alkene synthesis because of its ability in forming double bonds at precise positions. Our popular products such as Ethyl 2-[Bis(2,2,2-trifluoroethyl)phosphono] Propionate and p-Xylylenebis(triphenylphosphonium chloride) are typically available for immediate shipment. View detailed information on all our available Wittig Reagents by linking to the specific product blocks.
