The use of the Tp(iPr(2)) ligand led to the straightforward and high-yield synthesis of rare examples of trinuclear monoligand lanthanide dihydrides, (Tp(iPr(2)))LnH(2) (Ln = Y, Lu). The Y complex was found to mediate the hydrogenation and coupling of carbon monoxide with exclusive formation of propene via the intermediacy of a cluster-bound propenolate ligand.
Tp(iPr(2))配体的使用导致了罕见的三核单核镧系元素二氢化物的直接高产合成,(Tp(iPr(2)))LnH(2)(Ln = Y,Lu)。发现 Y 配合物通过中间体与一氧化碳的加氢和偶联反应,通过中间体与配位的丙烯酸盐配体,以独特的方式形成丙烯。
