A series of vinylgold(I) complexes [Au(CR=CHR)L] (R = H, Me; L = PPh3, PPh2Me, PPhMe2) were prepared from the reaction of the Grignard reagents [MgBr(CR=CHR)] (R = H, Me) with the gold(I) phosphane complexes [AuCl(L)] (L = PPh3, PPh2Me, PPhMe2) at low temperature. The complexes were characterised by various spectroscopic techniques and, in the case of [Au(CMe=CHMe)(PPh3)], by a single-crystal X-ray
由格氏试剂[MgBr(CR=CHR)]反应制备了一系列乙烯基金(I)配合物[Au(CR=CHR)L](R = H, Me; L = PPh3, PPh2Me, PPhMe2) ( R = H, Me) 与金 (I) 磷烷络合物 [AuCl(L)] (L = PPh3, PPh2Me, PPhMe2) 在低温下。这些配合物通过各种光谱技术进行表征,在 [Au(CMe=CHMe)(PPh3)] 的情况下,通过单晶 X 射线结构测定进行表征。这些乙烯基金 (I) 配合物的金-碳键很容易被酸裂解,并且在高锰酸钾的存在下,被含有酸性质子的物质裂解。(© Wiley-VCH Verlag GmbH & Co.
