Stannaneselone Tbt(Tip)Sn=Se (Tbt = 2,4,6-trisphenyl; Tip = 2,4,6-triisopropylphenyl), a novel compound containing a tin-selenium double bond was synthesized by the reaction of the corresponding stannylene Tbt(Tip)Sn with elemental selenium.It reacted with phenyl isothiocyanate, mesitonitrile oxide and styrene oxide to afford cycloadducts.In the reaction with phenyl isothiocyanate, 1,3,2-dithia- and diselenastannetanes were obtained instead of the expected 1,3,2-thiaselenastannetane.Another approach to the stannaneselone by deselenation of the corresponding 1,2,3,4,5-tetraselenastannolane with triphenylphosphine is also described.Keywords: Tin; Selenium; Bulky ligand; Stannylene; Cycloaddition; Stannaneselone
