2-Acetamidohexafluoro-2-propanol (HAcfp), CH3CONHC(CF3)2OH, may act as a bidentate, uninegative, ligand to give complexes of the type M(Acfp)2 (M = Co2+, Ni2+, Cu2+, Zn2+); M(Acfp)3 (M = Fe3+); M(Acfp)4 (M = Ce4+); or [M(Acfp)4]− (M = lanthanide(III)). Coordination is through the two oxygen atoms, except in the case of copper, where nitrogen also enters into coordination. In the complex Cu(Acfp)2,
2-乙酰氨基六氟-2-丙醇 (HAcfp)、CH3CONHC(CF3)2OH 可作为双齿单负配体生成 M(Acfp)2 型配合物(M = Co2+、Ni2+、Cu2+、Zn2+);M(Acfp)3 (M = Fe3+); M(Acfp)4 (M = Ce4+); 或 [M(Acfp)4]- (M = 镧系元素 (III))。配位是通过两个氧原子进行的,除了在铜的情况下,氮也进入配位。在络合物Cu(Acfp)2中,酰胺质子可以用NaH去除得到Na2[Cu(Acfp)2],它与羰基发生加成反应。甲酰胺同样与六氟丙酮反应得到HCONHC(CF3)2OH,其以与 HAcfp 相同的方式与铜螯合,而琥珀酸二酰胺与六氟丙酮反应生成化合物 [-CH2CONHC(CF3)2OH]2,其作为四齿、双负性配体。
