混合金属簇(PhC≡CPh)(PhCH=CPh)Co_3Ru(CO)_9和(PPh_3)Fe_2Co(CO)_7(NO)S的合成与表征

SYNTHESIS AND CHARACTERIZATION OF THE MIXED METAL CLUSTERS OF (PhC=CPh)(PhCH = CPh)Co_3Ru(CO)_9 AND (PPh_3)Fc_2Co

对于羰基混合金属簇的合成,利用配体的交换反应,制备含有不同配体的羰基混合金属簇。配体取代后的羰基金属簇的性质发生了变化,如可逆氧化还原性质,催化活性与选择性等。由于过渡金属原子的性质各不相同,配位取代反应也有很大差异,所以研究配体取代反应,制备含有不同配体的羰基过渡金属簇成为金属簇化学的重要组成部分。

HCo3Ru(CO)12 and Fe2Co(CO)8(NO)S reacted with diphenylacetylene and triphcnyl-phosphine in hexane to give (PhC CPh)(PhCH CPh)Co3Ru(CO)9 and (PPh3)Fe2Co (CO)7(NO)S respectively in high yield. In this paper, these two compounds were characterized by IR, UV, 1H, 31P NMR, the elemental analysis and melting point were determined. The structures and coordinations of both clusters have been described.
