Earth-abundant and well-defined iron complexes are found to be cheap and effective catalysts for a series of “umpolung” nucleophilic additions of hydrazones. The new catalytic system not only maintains the broad substrate scope of an earlier expensive ruthenium system but also attains chemoselectivity of different kinds of carbonyl groups. Furthermore, the iron catalyst enables this reaction at ambient
发现富含地球的铁和定义明确的铁络合物对于一系列“ ”亲核加成be而言,是廉价且有效的催化剂。新的催化系统不仅保持了较早的昂贵钌系统的广泛底物范围,而且还获得了不同种类羰基的化学选择性。此外,铁催化剂能够在环境温度下进行该反应。
