The compound [Ph2N3C2(C3F7)2]HgCH3 was synthesized from Na[Ph2N3C2(C3F7)2] and CH3HgCl. In solution, it exists as a mixture of two isomers that interconvert slowly on the NMR time scale. Both isomers feature a η1-Ph2N3C2(C3F7)2 ligand. In the asymmetrical one, the CH3Hg group is bonded to one of the two terminal nitrogen atoms. In the more stable symmetrical isomer, [PhNC(C3F7)]2NHgCH3, mercury is
由Na [Ph 2 N 3 C 2(C 3 F 7)2 ]和CH 3 HgCl合成化合物[Ph 2 N 3 C 2(C 3 F 7)2 ] HgCH 3。在溶液中,它以两种异构体的混合物形式存在,它们在NMR时间尺度上缓慢相互转化。两种异构体设有η 1 -Ph 2 Ñ 3 Ç 2(C 3 ˚F 7)2
配体。在不对称的CH 3中Hg基团键合到两个末端氮原子之一上。在更稳定的对称异构体[PhN C(C 3 F 7)] 2 NHgCH 3中,
汞连接到中心氮原子上。正是这种异构体结晶,并通过X射线衍射进行了表征。通过DNMR光谱获得CH 3 Hg转化反应的热力学参数。分析了19 F NMR谱。在[Ph 2 N 3 C 2(C 3 F 7)2 ] AuPPh 3中未观察到
