摘要: 通过α-萘基、α-噻吩基和取代苯基苯乙炔与Co2(CO)8的络合反应以及对氨基苯基苯乙炔六羰基二钴与乙酰氯的N-乙酰化反应,合成了十二个新的二芳基乙炔六羰基二钴络合物。实验表明,氨基对位的钴碳簇核PhC2Co2(CO)6对苯胺的亲核活性无显著影响。

Abstract: 12 New diarylacetylenedicobalt hexacarbonyl complexes have been synthesized by complexation reaction of α-naphthyl, α-thienyl or substituled-phenyl phenylace-tylene with Co2(CO)8and N-acetylalion of p-aminophenyl phenylacetylenedicobalt hexacarbonyl. The structures of all the complexes were characterized by elemental analysis, IRand 1HNMR spectroscopy. Through comparison of N-acetylation of p-aminophenyl phenylacetylenedicobalt hexacarbonyl and aniline under comparable conditions, it was found that the cluster core PhC2Co2(CO)6para to an amino group attached to aromatic ring does not obviously affect the nucleophilicily of aniline.
