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类化合物与五羰基铁（Fe(CO)5）、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。该类双核金属配合物与碘（I2）发生反应时，同样可得到不同的金属碘化物配合物。
