As the aluminate base [LiAl(TMP)(2)(iBu)(2)] 1 displays halogen tolerance towards substituted aromatics, 4-halo-anisoles have been ortho-aluminated and electrophilically quenched to form synthetically useful multi-heterohalogenated anisoles, with the Al intermediates along the route structurally defined.
由于铝酸盐基质[LiAl(
TMP)(2)(iBu)(2)] 1对取代的芳族化合物显示卤素耐受性,因此对4-卤代
苯甲醚进行了邻铝化并进行了亲电淬灭,从而形成了合成上有用的多杂卤代
异氰酸酯,沿路线定义的Al中间体。
