Literature References

Reagent for the oxy-selenation of alkenes in the presence of 2-3 equivalents of water and an acid catalyst: J. Am. Chem. Soc., 101, 3704 (1979). The trans-ß-hydroxy selenide products are useful intermediates, e.g. in the synthesis of allylic alcohols by selenoxide elimination. In general, the reagent is superior to the corresponding halides in intramolecular cyclization reactions with unsaturated acids, urethanes, etc. Even suitably disposed ketones may undergo cyclization of the enol form, in the presence of SnCl4: J. Chem. Soc., Chem. Commun., 1251, 1252 (1982):
