Aliphatic C–H bond functionalization is at the frontline of research because it can provide straightforward access to simplified and cost-effective synthetic procedures. A number of these methodologies are based on hydrogen atom transfer (HAT), which, as a consequence of the inert character of C–H bonds, often represents the most challenging step of the overall process. Because the majority of organic molecules contain multiple nonequivalent C–H bonds that display similar chemical properties, differentiating between these bonds with high levels of selectivity represents one of the most challenging issues. Clarification of the factors that govern the relative reactivity of C–H bonds toward HAT reagents is thus of primary importance in order to develop selective functionalization procedures.

对基于氢原子转移的脂肪族C–H键加氧的选择性的探索

脂肪族C–H键功能化处于研究的前沿,因为它可以提供直接访问简化且具有成本效益的合成程序的途径。这些方法中有许多是基于氢原子转移(HAT)的,这是C–H键惰性的结果,通常代表整个过程中最具挑战性的一步。由于大多数有机分子都包含多个显示相似化学性质的不等价的C–H键,因此以高选择性将这些键区分开是最具挑战性的问题之一。因此,阐明控制C–H键与HAT试剂的相对反应性的因素对于开发选择性功能化程序至关重要。
