资源简介:
The addition of THF solutions of tBuMgCl to SnCl4 in varying solvents (S) results in a dramatic change of the predominant product obtained Cl(tBu2Sn)nCl (n = 1–3). For S = THF the product obtained was tBu2SnCl2, S = toluene, benzene yields Cl(tBu2Sn)2Cl, while for S = hexane the tristannane Cl(tBu2Sn)3Cl was isolated in 45% yield. The last compound is photochemically sensitive when irradiated at 350 nm to form Cl(tBu2Sn)2Cl. Irradiation of this latter material with a 254 nm lamp results in the formation of tBu2SnCl2.
