在我们的手中,Fe(II)或(III)吡啶配合物在铃木联芳基交叉偶联反应中没有显示出活性,除了在一个不可再现的情况下,当观察到完全转化。在相同条件下与乙酸钯的比较表明,在S:C比为1,000,000:1时可以获得完全转化,因此必须非常小心,以防止痕量Pd污染物引起的“假阳性”。(C)2009爱思唯尔有限公司版权所有。
In our hands, Fe(II) or (III) pyridine complexes show no activity in Suzuki biaryl cross-coupling reactions, except in one irreproducible instance when complete conversion was observed. A comparison with palladium acetate under the same conditions showed that complete conversion can be obtained in a S:C ratio of 1,000,000:1 and therefore extreme caution must be exercised to prevent 'false-positives' arising from trace Pd-contaminants.
