C-H键的官能化尚未在合成化学中获得广泛应用,部分原因是缺乏在其他官能团存在下起作用的合成试剂。这些问题已经在酶中被克服,其具有有效地和选择性地裂解C-H键的金属-氧代活性位点。如何高能量的金属氧瞬态物种可以执行这样的高保真度困难的转换是讨论在本教程审查。突出显示的是氧化还原电位和金属-氧代碱度对C-H键活化之间的关系,如在一系列生物启发的锰-氧代络合物中所见。
The functionalization of C–H bonds has yet to achieve widespread use in synthetic chemistry in part because of the lack of synthetic reagents that function in the presence of other functional groups. These problems have been overcome in enzymes, which have metal-oxo active sites that efficiently and selectively cleave C–H bonds. How high-energy metal-oxo transient species can perform such difficult transformations with high fidelity is discussed in this tutorial review. Highlighted are the relationships between redox potentials and metal-oxo basicity on C–H bond activation, as seen in a series of bioinspired manganese-oxo complexes.
