complex catalyst using water as the hydrogen source without a sacrificial reductant. Mechanistic investigations suggest that bromine atom abstraction via a rhodium porphyrin metalloradical operates to give the rhodium porphyrin alkyl species and the subsequent hydrolysis of the rhodium porphyrin alkyl species to a hydrocarbon product is a key step to harness the hydrogen from water.
通过使用水作为氢源而没有牺牲还原剂的铑卟啉配合物催化剂成功地实现了烯丙基和苄基溴的加氢脱溴。机理研究表明,通过铑卟啉金属骨架提取溴原子可得到铑卟啉烷基物质,随后铑卟啉烷基物质水解为烃产物是从水中利用氢的关键步骤。
