Process for the preparation of alkali metal diaryl phosphides, characterized in that alkali metal diaryl phosphides of the formula (R₉)₂PM are prepared by reacting, in liquid ammonia, an alkali metal M with a triaryl phosphine of the formula (R₉)₃P, in which formulae R₉ represents an aryl group containing one or more polar substituents which can occupy no other positions in respect to the phosphorus atom than the two meta positions and one of the ortho positions.
