    • 3SiH (2.2 mmol), and AIBN (0.2 mmol) was refluxed in dry benzene (40 mL) under argon. After completion of the reaction (t.l.c.), the solvent was evaporated to give an oil which was purified by flash chromatography to yield product 3. A four-fold excess of TTMSS was needed when selenoester was used as crude product.
