WERKWIJZE TER BEREIDING VAN EEN O-(DI(ALK)ARYLFOSFINO)BENZOEZUUR.

摘要

Ortho-dihydrocarbylphosphinobenzoic acids are produced in high yield substantially free of the corresponding meta-isomer by substantially immediate intimate contacting of sodium dihydrocarbyl phosphide and phenyl sodium with an ortho-chlorobenzoate in an inert solvent solution to produce the sodium salt of o-dihydrocarbylphosphinobenzoic acid, which is thereafter converted to the free acid by treatment with mineral acid.
