for the decarboxylative oxygenation of carboxylic acids using a non-heme manganese catalyst under blue light irradiation with O2 as the sole oxidant. Featuring mild reaction conditions, the protocol allows readily available carboxylic acids to be converted into a wide variety of valuable aldehydes, ketones and amides. Mechanistic studies indicate that the decarboxylation and oxygenation involves the formation
本文报道了一种使用非血红素锰催化剂在蓝光照射下以 O 2作为唯一氧化剂的羧酸脱羧氧化的新方案。该协议具有温和的反应条件,可将现成的羧酸转化为各种有价值的醛、酮和酰胺。机理研究表明,脱羧和氧化涉及活性锰氧物质的形成。
Herein, we present a decarboxylative nucleophilic fluorination of carboxylicacids with a silver catalyst. This strategy enables the synthesis of a myriad of diverse and valuable fluorinated motifs under mild conditions, demonstrating good functional-group tolerance and utility in late-stage functionalization. In contrast to traditional electrophilic fluorination, this nucleophilic method utilizes
of 1,n-dicarbonyl compounds through the homolytic C–C bond cleavage of unstrained carbocyclic and heterocyclic ring systems. This method exhibits a lot of synthetic advantages including mild conditions, simple operation, and convenience of amplification. Mechanistic studies support the generation of peroxy radical species via oxygen capture followed by radical fragmentation.
