Reactions of Pyridyl Side-Chain-Functionalized Cyclopentadienes with Metal Carbonyl: Intramolecular C−H Activation of Pyridine

Thermal treatment of the pyridyl side-chain-functionalized cyclopentadienes with Fe(CO)5 and Ru3(CO)12 gave
different intramolecular C−H activated products, in addition
to the normal dinuclear metal complexes. Reactions of the
dinuclear metal complexes with I2 also gave different metal
iodide complexes.

将吡啶侧链功能化的环戊二烯与五羰基铁[Fe(CO)₅]和十二羰基三钌[Ru₃(CO)₁₂]进行热处理，除得到常规双核金属配合物外，还获得了不同的分子内C-H活化产物。上述双核金属配合物与碘单质(I₂)反应，也可得到不同的金属碘化物配合物。
