chelating bis(aryloxide) ligands is described and demonstrated by the synthesis of 2,2'-ethylenebis(6-isopropylphenol) (1, H(2)BIPP) and transition metal complexes of its dianion. The utility of these ligands in titanium and tantalum organometallic chemistry is shown in the alkylation of (BIPP)TiCl(2) (7) to form (BIPP)TiMe(2) (8) and (BIPP)Ti(CH(2)Ph)(2) (9) and in the alkylation of (BIPP)TaCl(3) (10) and
通过合成2,2'-亚乙基双(6-异丙基苯酚)(1,H(2)BIPP)及其二价阴离子的过渡金属配合物,描述并证明了一种空间调谐的螯合双(芳氧基)配体的新途径。在(BIPP)TiCl(2)(7)的烷基化反应中形成(BIPP)TiMe(2)(8)和(BIPP)Ti(CH(2)Ph)的烷基化显示了这些配体在钛和钽有机金属化学中的效用)(2)(9)以及在(BIPP)TaCl(3)(10)及其碱加合物的烷基化反应中形成(BIPP)TaMe(3)(14)和(BIPP)Ta(CH(2)Ph) (3)(13)。在(BIPP)TaCl( 3)(THF).THF(11.THF)和(BIPP)Ta(CH(2)C(6)H(5))(3)(13)。
