Heterobimetallic (di)benzoindenyl Re–Cr complexes have been prepared by a sequence starting from (8-bromobenzo[e]-indenyl)potassium. Reaction with pentacarbonylrhenium bromide affords tricarbonylrhenium complex 2, which has been modified to rhenium–chromium carbene complex3. Its chromium-templated [3 + 2 + 1]benzannulation afforded the anti(Cr(CO)3–Re(CO)3) dibenzoindenyl complex 4 as the major product along
异双金属(二)苯并茚基Re-Cr络合物是通过从(8-溴苯并[ e ]-茚基)钾开始的序列制备的。与五羰基溴化反应,可制得三羰基complex络合物2,该化合物已被改性为rh-铬卡宾络合物3。它的铬模板[3 + 2 + 1]苯甲酸酯化提供了抗(Cr(CO)3 -Re(CO)3)二苯并茚基配合物4作为主要产物以及顺式非对映异构体5。通过X射线分析建立了所有异双金属配合物的分子结构。
