One-Pot Synthesis of Indoles and Aniline Derivatives from Nitroarenes under Hydrogenation Condition with Supported Gold Nanoparticles
摘要:
One-pot sequences of hydrogenation/hydroamination to form Indoles from (2-nitroaryl)alkynes and hydrogenation/reductive amination to form aniline derivatives from nitroarenes and aldehydes were catalyzed by Au nanoparticles supported on Fe2O3. Nitro group selective hydrogenations and successive reactions were efficiently catalyzed under the conditions.
通过选择性能量转移催化产生了一种新型的sp 3类N 中心自由基。在光激发下,在 Ir 配合物存在下N-吲哚碳酸酯的均裂 N-O 键断裂产生以 N 和 O 为中心的自由基。吲哚 C3 位的高自旋密度导致自由基与以 O 为中心的自由基复合,从而提供有价值的 3-氧吲哚衍生物而无需脱羧。还证明了所需产物向各种分子的转化。

A new type of sp3-like N-centered radical has been generated by selective energy transfer catalysis. Upon photoexcitation, homolytic N–O bond cleavage of N-indolyl carbonate in the presence of an Ir complex produced N- and O-centered radicals. The high spin density at the C3 position of indole led to radical recombination with the O-centered radical, affording valuable 3-oxyindole derivatives without
