Knittle et. al. propose perovskite is stable, whereas Mao et. al. consider it will transform to the mixture of magnesiowüstiteO and stishovite due to temprature effect.

例如，Knittle等人认为，钙钛矿型SiO〓是稳定的，在整个下地幔中可保持为单一相态；但Mao等人认为，由于温度的影响，它也可能转变成方镁石O与斯石英SiO〓的混合物相态。

Although multidentate heteroatomic could catalyse high selectivity of α-olefin such as 1-hexene and 1-octene,these ligand usually use expensive co-catalyst such as MAO,so it hardly has broad application in α-olefin field.

但由于多齿杂原子配体一般需由价格相对昂贵的烷基铝氧烷，特别是MAO的活化才可进行高效催化反应，因此长期以来多齿型配体难以得到广泛应用。
