Abstract: The phenylated group 13/15 compounds, Ph2MEPh2 (M = Ga and In; E = P and As), were prepared from the reaction of Ph3M (M = Ga and In) with Ph2EH (E = P and As) in 73–83% yield. Pyrolysis of Ph2GaAsPh2 and Ph2GaPPh2 at 450°C produced crystalline GaAs and GaP, which were characterized by x-ray powder diffraction. The effect of temperature on the synthesis of GaAs and GaP was investigated. Phenyl-group migration is the dominant reaction pathway en route to GaAs and GaP.
