The presence of a chelating tether attached to ethylguanine leads to the formation of a metalâcarbon bond at C8 of the nucleobase when reacted with trans-[RuCl4(dmso)2]â, in contrast, more typical co-ordination at N7 is seen in the absence of the tether.
当与反式-[RuCl4(dmso)2]反应时,连接到乙基
鸟嘌呤的螯合链的存在导致在核碱基的 C8 处形成
金属-碳键,相反,更典型的配位在N7 在没有系绳的情况下可见。
