Novel N-Nucleophilic Addition to and Ring-Breaking of Coordinated Cyclooctatetraene in Diiron Bridging Carbyne Complexes
摘要:
The reactions of the diiron cationic carbyne complexes 1-3 with NaN(SiMe3)(2) or LiN(SiMe3)(2) in THF at low temperature give novel N-nucleophilic addition products, the neutral diiron bridging carbyne complexes 4-6, while the reactions of 1-3 with LiNEt2 lead to breaking of the COT ring to produce the diiron bridging carbene inner salts 7-9, among which the structures of 4 and 7 have been established by X-ray diffraction studies.
