Several fluorinated aluminum tris(2,6-diphenylphenoxide) (ATPH) derivatives have been synthesized to evaluate, as functionalized Lewis acid receptors, the conjugate alkylation ability to α,β-unsaturated aldehydes by the combined use of alkyllithium nucleophiles. Among these, 3,4,5-F3-ATPH was found to be the most satisfactory.
已经合成了几种氟化三(2,6-二苯基苯氧基铝)(ATPH)衍生物,以评估作为官能化的路易斯酸受体,通过烷基锂亲核试剂的联合使用,对α,β-不饱和醛的共轭烷基化能力。其中,最令人满意的是3,4,5-F 3 -ATPH。
