Isolation and structural characterisation of monoprotonated 1,2-bis(diphenylphosphino)benzene in its tetrabromogallate(III) salt

摘要

Hydrolysis of gallium tribromide complexes of 1,2-bis(diphenylphosphino)benzene in toluene solvent affords crystals of the mono-phosphonium salt [1,2-Ph2P-(C6H4)-PPh2H](+) [GaBr4](-). The structure analysis by single crystal X-ray diffraction allows an internal comparison of Ph2P phosphino and Ph2PH+ phosphonium functions. [References: 14]
