Convenient Access to Homo- and Heterobimetallic Alkoxo Hydridozinc Clusters of Formula [(HZnOtBu)4-n(LiOtBu)n] (n = 0, 1, 2, 3)
摘要:
A convenient and efficient route to the stable and soluble alkoxo hydridozinc clusters {[HZnOtBu](3)[Li(thf)OtBu]}, {[HZnOtBu](2)[Li( thf)OtBu](2)}, and {[HZnOtBu][Li(thf)OtBu](3)} is described by cluster core metathesis reactions between [HZnOtBu](4) and [LiOtBu] aggregates in THF solutions. They are the first examples of alkoxo hydridozinc clusters structurally characterized and consist of heterocubane cores.
