乙酰丙酮配合物

金属的乙酰丙酮配合物是金属离子(通常是过渡金属)与乙酰丙酮阴离子(CH3COCHCOCH3)形成的配合物,通常简写为M(acac)x。通常,两个氧原子都与金属结合形成六元螯合环。乙酰丙酮上连接有取代基的配合物RCOCHCOR′)也是已知的。[1]与相应的金属卤化物不同的是,乙酰丙酮配合物可溶于有机溶剂。这些性质使乙酰丙酮配合物可以用作催化剂前体和金属试剂,如用作NMR的“转移试剂”、有机合成的催化剂、工业上加氢甲酰化催化剂前体等。在一些情况下,C5H7O2还可以通过中心的原子与金属结合,这种键合模式对于第六周期的过渡金属如Pt(II)和Ir(III)则更为常见。

不同金属的乙酰丙酮配合物如下所示:
