Uses | Benzyltriphenylphosphine chloride is used as an organic synthesis reagent for several compounds, including stable phosphine ylide containing saturated oxygen heterocyclic ring, and also used to synthesize new substituted cis-stilbene derivatives with antibacterial activity. It is used as a vulcanizing agent for fluororubber in combination with bisphenol AF. |
