Halogen sulfur—oxygen bonds

Sulfoxides Z =S=0 1075-1040 (vs) 730-690 (var) 395-360 (var) Halogen or oxygen atom bonded to sulfur increases the frequency. 

Two types of electrons are responsible for the absorption of ultraviolet and visible radiation by organic molecules (1) shared electrons that participate directly in bond formation and are thus associated with more than one atom and (2) unshared outer electrons that are largely localized about such atoms as oxygen, the halogens, sulfur, and nitrogen (Skoog et al., 1992).

The silicon-halogen, silicon-oxygen, and silicon-sulfur bonds of the haiogenosil-anes, siiyl ethers, and siiyi thioethers are cleaved by reaction with LAH, AIH3, or DIBAH, and the corresponding siiyl hydrides are obtained [CGI, CG2]. Ultrasound activation can be applied [LG2] (Figure 5.9), Anionic pentacoordinated silicon compounds are reduced to hydrogenosilanes by LAH or DIBAH [BC6]. 

Organic sulfur compounds in which sulfur is bonded to a heteroatom other than oxygen have not been widely studied by photoelectron spectroscopy. Those studies which have been reported mostly involve either nitrogen or a halogen as the heteroatom.
