摘要

The disodium salt of a bis (aryloxide)-N-heterocyclic-carbene dianionic ligand, Na2 [L], was prepared by reaction of 1, 3-bis (4, 6-di-tert-butyl-2-hydroxybenzyl) imidazolium bromide [H3L] Br with 3 equiv. of NaN (SiMe3) 2. Reaction of ZrCl4 (thf) 2 with 1 equiv. of Na2 [L] gave a mixture of [L] ZrCl2 (thf)(1) and [L] 2Zr (2). When the amount of Na2 [L] was increased to 2 equiv., the bis (bis (aryloxide)-N-heterocyclic-carbene) complex 2 was obtained in ...
