Cyclohexylphosphine → Cyclohexyldichlorophosphine

Participants

Reaction Steps

319 g (1.05 mol) of a 38 wgt % monocyclohexylphosphine solution in toluene was added dropwise at 25° C. to a suspension of 436 g PCl5 (2.1 mol) in 1 liter toluene. After the strongly exothermal reaction was complete, the reaction mixture was filtered using a reverse frit. 5 g orange colored solid matter remained behind. The clear solution (31P-NMR; δ P: 195 ppm, C6H11PCl2, 95 mol %) was distilled under vacuum.
