Synthesis of new water-soluble phosphonium salts and their Witting reactions in water

摘要

Some new water-soluble alkyltriarylphosphonium salts are reported.Their solubility is due to the presence of either carboxy or hydroxy groups on the phenyl rings attached to phsophorus. Examples of both benzyland butylphosphonium salts are presented and investigation into their Wittig reactions with a range of aldehydes using water as the solvent is descrbed.
