Chlorodiisopropylphosphine

Chlorodiisopropylphosphine is an organophosphorus compound with the formula ()2PCl. It is a colorless liquid that is used to prepared phosphine ligands.
==Synthesis and reactions==
The compound is prepared by treating phosphorus trichloride with the Grignard reagent derived from isopropyl chloride:〔W. Voskuil and J. F. Arens "Chlorodiisopropylphosphine" Org. Synth. 1968, volume 48, 47. 〕
:PCl3 + 2 (CH3)2CHMgCl → ()2PCl + 2 MgCl2
Relative to the reaction of less hindered Grignard reagents with PCl3, this reaction affords a superior yield of the monochloro derivative.
Chlorodiisopropylphosphine reacts with alcohols and phenols to give phosphonites, this reaction typically is conducted in the presence of a base:
: ()2PCl + ROH → ()2POR + HCl
Phosphinites are versatile ligands.〔for example: Pandarus, V., Zargarian, D., "New Pincer-Type Diphosphinito (POCOP) Complexes of Nickel", Organometallics 2007, volume 26, 4321. 〕
