Venturello, P.; Barbero, M.Science of Synthesis, (200681433.

Treatment of 4-iodo- or 4-bromotoluene with potassium diphenylphosphide in refluxing ammonia or dimethyl sulfoxide at 25°C gives diphenyl(4-tolyl)phosphine (89) in good yields (Scheme 46).[‌59‌] The reaction occurs in the dark, but is stimulated by broad-spectrum UV irradiation.
