Transition metal complexes have been synthesized by using a newly developed bulky monodentate aryloxide ligand based on a rigid fused-ring s-hydrindacenyl skeleton. Their molecular structures have been confirmed by X-ray crystallography. The new cationic zirconium complexes showed an improved catalytic ability for hydrosilylation of carbon dioxide, comparing with those of the previously reported catalysts having multidentate ligands. Theoretical calculations were performed to examine the reaction mechanism for the chemical reduction of carbon dioxide. Also olefin polymerization reactions have been studied with the use of cationic transition complexes.

过渡金属配合物已通过使用基于刚性融合的S-羟基苯基骨架的新发达的笨重的单次芳氧化物配体合成。它们的分子结构已通过X射线晶体学证实。与先前报道的具有多同化配体的催化剂相比，新的阳离子锆复合物具有提高二氧化碳氢硅化的催化能力。进行了理论计算以检查二氧化碳化学还原的反应机制。还研究了使用阳离子过渡复合物的烯烃聚合反应。
