Transition metal catalysis represents a relatively unexplored but potentially useful route to form bonds between main group elements. Previous work in the area of amine-borane adduct dehydrocoupling has exclusively employed late transition metal (e.g., Rh) catalysts which were found to predominantly operate via a heterogeneous mechanism. Herein, we present a new, early transition-metal-catalyzed, homogeneous system which exhibits higher activity.
过渡金属催化是一种在主族元素之间形成化学键的相对未被充分探索但可能有用的途径。此前在胺硼烷加合物脱氢偶联领域的工作仅使用了后过渡金属(如铑)催化剂,发现其主要通过多相机制起作用。在此,我们展示了一种新型的、由早期过渡金属催化的均相体系,该体系具有更高的活性。
