calcium oxycyclopentadienide complex, which is the first alkaline earth metal complex containing an oxycyclopentadienyl dianion ligand. The η5, η1, and η2 interactions between the oxycyclopentadienyl dianion ligand and the calcium center were observed in the solid state. The calcium oxycyclopentadienide complex displayed reductive character and multiple reactive sites. Its reactivity toward a range of
9-芴醇与Ca [N(SiMe 3)2 ] 2的直接去质子反应有效地产生了芴基的氧环戊二烯酸钙络合物,这是第一个含有氧环戊二烯基二价阴离子配体的碱土金属络合物。的η 5,η 1,η 2间的二价阴离子oxycyclopentadienyl配体和钙中心之间的相互作用在固体状态下进行观察。氧合环戊二烯酸钙复合物表现出还原特性和多个反应位点。研究了它对一系列亲电子试剂,特别是酰基氯的反应性,并进行了详细讨论。合成了多种芴衍生物。
