已经开发了利用明确定义的 Bi(I) 配合物作为催化剂和氨硼烷作为转移剂的催化转移氢化。这种转变代表了氧化态 I 和 III 之间的低价色素原催化循环的独特例子,并被证明可用于偶氮芳烃的氢化和硝基芳烃的部分还原。有趣的是,铋烯催化剂在低价过渡金属敏感官能团的存在下表现良好,并且与类似的磷基催化相比表现出正交反应性。机理研究表明,一种难以捉摸的铋物种的中间体,被认为是氢化和氢形成的原因。
A reduction method involving sodium borohydride and cobalt sulfate dissolved in aqueous ethanol was developed and optimized. The established method reduces alkenes, alkynes, azides, nitriles, and nitroarenes at high rates (3–10 min) to afford good to excellent yields of the corresponding target reduction products.

A direct Fe-catalyzed alpha-amination of 1,3-dicarbonyl compounds :has been accomplished using, arylhydroxylamines as aminating agents, This novel protocol allows convenient access to alpha-amino carbonyl derivatives without the need for any postreaction manipulations. This is an operationally simple procedure that works at low temperatures in shorter reaction times and produces high yields with excellent N-selectivity.
