Reductive cleavage of aromatic and benzylic C–O bonds by chromium catalysis is reported. This deoxygenative reaction was promoted by low-cost CrCl2 precatalyst combined with poly(methyl hydrogen siloxane) as the mild reducing agent, providing a strategy in forming reduced motifs by cleavage of unactivated C–O bonds. A range of functional groups such as bromide, chloride, fluoride, hydroxyl, amino,
据报道,铬催化还原性裂解芳香族和苄基 C-O 键。这种脱氧反应由低成本的 CrCl2 预催化剂与作为温和还原剂的聚(甲基氢硅氧烷)结合促进,提供了一种通过裂解未活化的 C-O 键形成还原基序的策略。一系列的官能团如溴、氯、氟、羟基、氨基和烷氧基羰基可以保留在还原过程中。
