Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa)Infobox references Dichlorophenylphosphine is an organophosphorus compound with the formula C6H5PCl2. This colourless viscous liquid is commonly used in the synthesis of phosphine ligands.
Dichlorophenylphosphine is commercially available. It may be prepared by a electrophilic substitution of benzene by phosphorus trichloride, catalyzed by aluminium chloride.[1] The compound is an intermediate for the synthesis of other chemicals for instance dimethylphenylphosphine:
- C6H5PCl2 + 2 CH3MgI → C6H5P(CH3)2 + 2 MgICl
Dichlorophenylphosphine undergoes the McCormack reaction upon treatment with dienes to give phospholes.
