Phosphorus-Recycling Wittig Reaction: Design and Facile Synthesis of a Fluorous Phosphine and Its Reusable Process in the Wittig Reaction
phosphorus sources can be recycled using the appropriate fluorous phosphine in the Wittigreaction. The designed fluorous phosphine, which has an ethylene spacer between its phosphorus atom and the perfluoroalkyl group, was synthesized from air-stable phosphine reagents. The synthesized phosphine can be used for the Wittigreaction process to obtain various alkenes in adequate yields and stereoselectivity
