MeOC6H4CH2CH(COOEt)2, the synthesis of the tripod-ligand HOC6H4CH2C(CH2PPh2)3, 12, functionalized with a phenolic group at its backbone, is achieved in a few steps. Ether derivatives of 12 show the normal coordination behavior of RC(CH2PPh2)3. Thus MeOC6H4CH2C(CH2PPh2)3 forms the complexes [7·Fe(NCMe)3] (BF4)2 (8) and 7·Mo(CO)3 (9). The phenolate derived from 12 by deprotonation reacts with the CH2Cl groups
开始从4- methoxybenzylmalonic酯MeOC 6 ħ 4 CH 2 CH(COOEt烷基)2,所述的合成三脚架配体HOC 6 H ^ 4 CH 2 C(CH 2 PPH 2)3,12,在其主链上具有酚基官能化,只需几个步骤即可实现。12的醚衍生物显示RC(CH 2 PPh 2)3的正常配位行为。因此,MeOC 6 H 4 CH 2 C(CH 2 PPh 2)3形成配合物[ 7 ·Fe(NCMe)3 ](BF 4)2(8)和7 ·Mo(CO)3(9)。通过去质子化而衍生自12的酚盐与Merrifield树脂的CH 2 Cl基反应以高效地形成共价固定的聚合物12。聚合物结合的三脚架配体会经历三脚架典型的配位反应。除了通常的光谱和分析技术外,还使用12以及8和9的衍生物的X射线分析来鉴定产品。
