将TMEDA引入二甲基(氨基)锌酸锂“LiZn(NR 2)Me 2”中,在NR 2 = TMP的情况下,会产生TMEDA与锂结合的离散离子接触锌酸盐,但在NR 2 = HMDS的情况下,会产生TMEDA与锌结合的新型“反锌酸盐”,其中意外的是Me 2Zn(TMEDA)充当二聚体(LiHMDS)2分子的η1,μ配体,提供锯齿形链聚合物。
Introducing TMEDA to the lithium dimethyl(amido)zincates “LiZn(NR2)Me2” leads to a discrete ion-contacted zincate with TMEDA bound to lithium in the case of NR2 = TMP but to a novel “inverse zincate” with TMEDA bound to zinc in the case of NR2 = HMDS, where unexpectedly Me2Zn(TMEDA) functions as a η1,μ ligand to dimeric (LiHMDS)2 molecules to afford a zigzag chain polymer.
