Re2(CO)10 in decalin. The molecular structures of 9, 10, 12, and 13 were determined by X-ray diffraction analysis. These four crystals have similar molecular structures of the mononuclear carbonyl complex. In each of these molecules, Re is η5-coordinated to the five-membered ring of the indenyl group. Complexes 8–14 have catalytic activity for Friedel-Crafts reactions of aromatic compounds with a variety
摘要 配合物 [(η5-C9H6R)Re(CO)3] [R = nBu (8), tBu (9), CH(CH2)4 (10), Ph (11), Bz (12), 4-甲氧基苯基(13), 4-氯苯基 (14)] 通过回流取代茚基配体 [C9H7R] [R = nBu (1), tBu (2), CH(CH2)4 (3), Ph (4), Bz ( 5)、4-甲氧基苯基 (6)、4-氯苯基 (7)] 和 Re2(CO)10 在萘烷中。通过X射线衍射分析确定了9、10、12和13的分子结构。这四种晶体具有相似的单核羰基配合物的分子结构。在这些分子中的每一个中,Re 与茚基的五元环 η5 配位。配合物 8-14 对芳香族化合物与各种烷基化和酰化试剂的 Friedel-Crafts 反应具有催化活性。与传统催化剂相比,
