2,2,6,6-Tetramethylpiperidine-N-oxyl (TEMPO) has been extensively utilized as a radical scavenger or an oxidation catalyst. In contrast, TEMPO as a hydrogen atom transfer (HAT) catalyst has rarely been studied. Here, authors report that TEMPO, as the HAT catalyst, homolytically cleaves benzylic or allylic C-H bonds to give the corresponding alkyl radicals. Benefiting from the dual roles played by TEMPO as the HAT catalyst and the radical scavenger, the highly challenging aerobic dehydrogenation of activated alkanes to alkenes is successfully developed. In the experiment, the researchers used many compounds, for example, 2,3-Dihydrobenzo[b]furan (cas: 496-16-2SDS of cas: 496-16-2).
2,3-Dihydrobenzo[b]furan (cas: 496-16-2) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.SDS of cas: 496-16-2
