General procedure for the synthesis of diphenylchlorosilane from diphenylsilane: A mixture of 18.44 g (0.1 mol) of diphenylsilane (Ph2SiH2), 26.9 g (0.2 mol) of anhydrous copper chloride (CuCl2), 0.92 g (0.0048 mol) of anhydrous cuprous iodide (CuI), 80 g of ceramic balls, and 40 mL of diethyl ether was placed in a reactor at 50 °C using a mechanical stirrer at 400 rpm. The reaction was continued at room temperature for 2 hours. After completion of the reaction, the mixture was filtered and the filtrate was collected and concentrated. The concentrated residue was distilled under reduced pressure to give diphenylchlorosilane (Ph2SiHCl) (20.24 g, 92.6% yield) as a colorless liquid. Boiling point: 117 °C (210 Pa).1H NMR (δ, ppm): 5.82 (s, 1H, SiH), 7.47-7.76 (m, 10H, Si(C6H5)2).13C NMR (δ, ppm): 128.36, 131.10, 131.85, 134.52 (m, 12C, Si(C6H5)2). 29Si NMR (δ, ppm): -5.94 (s, 1Si, Ph2SiHCl).
