Abstract

The heterobimetallic aluminosilicate LAl(SLi)(micro-O)Si(OLi.2thf)(O(t)Bu)(2) was prepared from the LAl(SH)(micro-O)Si(OH)(O(t)Bu)(2) (L = HC{C(Me)N(Ar)}(2), Ar = 2,6-di-(i)Pr(2)C(6)H(3)) ligand, which can also be hydrolyzed to LAl(OH.thf)(micro-O)Si(OH)(O(t)Bu)(2)- leading to the first aluminosilicate-dihydroxide soluble in organic solvents.

摘要

异双金属铝硅酸盐[LAl(SLi)(μ-O)Si(OLi·2thf)(O(t)Bu)₂]₂由LAl(SH)(μ-O)Si(OH)(O(t)Bu)₂（L = [HC{C(Me)N(Ar)}₂]⁻，Ar = 2,6-二-(异丙基)₂C₆H₃）配体制备而成，该配体也可水解为LAl(OH·thf)(μ-O)Si(OH)(O(t)Bu)₂，从而得到第一种可溶于有机溶剂的铝硅酸盐-二氢氧化物。
