• phosphine
  • They are generated by the reaction of phosphine with formaldehyde in the presence of the mineral acid: PH3 + HX + 4 CH2O → [P(CH2OH)4+]X− A variety of phosphonium salts can be prepared by alkylation and arylation of organophosphines: PR3 + R'X → [PR3R'+]X− The methylation of triphenylphosphine is the first step in the preparation of the Wittig reagent.
