Chlorodiphenylphosphine Usage And Synthesis
  • Chemical PropertiesColorless to light yellow liqui
  • Synthesis Reference(s)Journal of the American Chemical Society, 77, p. 3526, 1955 DOI: 10.1021/ja01618a030
  • Purification MethodsThis air-sensitive, pale yellow lachrymatory liquid is purified by careful fractional distillation and discarding the lower boiling fraction which contains the main impurity PhPCl2 (b 48-51o/0.7mm), and checking for impurities by NMR.
