High-Pressure Assisted Synthesis of Fused Norbornenes Containing Two 7-Metallonorbornene Units

摘要

The high-pressure synthesis of new rod-like and U-shaped polycyclic compounds containing two 7-metallonorbornene (silicon or germanium) units fused to the 7-oxanorbornene rings is described.In addition,the structural features of adduct 9 established by X-ray structure determination and DFT calculations of model compounds are discussed.
