Popis:	Tris(methyltio)silane and tris(isopropylthio)silane effectively reduce a variety of organic substrates via free radical mechanisms. These silanes can also be used as hydrosilytating agents for alkenes having electron-donating substituents. The bond dissociation energy of the Si-H bonds have been measured by photoacoustic calorimetry and found to be around 83kcal mol -1 . The absolute rate constants for the reaction of the tert-butoxyl radical with (RS) 3 SiH have been measured by a laser flash photolysis technique and the optical absorption spectra of the corresponding radicals have been obtained
