triols were shown to disassemble selectively via an unexpected P–C bond cleavage reaction. This degradation pathway was effectively suppressed via complexation of Al3+ and Sc3+. In the resulting half-cage complexes, the ligand scaffold is bound to each metal (Al3+ and Sc3+, respectively) via all four donor atoms. So far, this κ4-P,O,O′,O″-coordination mode has not been observed for any other phosphino-triol
报道了马丁膦基三醇(两种衍生物)的修订合成。分离后,这些热敏三醇显示出通过意外的 P-C 键裂解反应选择性地分解。这种降解途径通过Al 3+和Sc 3+ 的络合被有效抑制。在得到的半笼络合物中,配体支架通过所有四个供体原子与每种金属(分别为Al 3+和 Sc 3+)结合。到目前为止,这κ 4 - P,Ô,Ô ',Ø “-coordination模式尚未观察到任何其他膦三醇。
