A visible-light-induced copper-catalyzedintermolecularhydroamination of alkenes using commercially accessible primary and secondary amines has been established. This effective method exhibits good tolerance of a broad range of functional groups and provides a facile access to an array of valuable amines with Markovnikov regioselectivity. The process can be positively expected to be used in bioactive

A photoinduced copper-catalyzed three-component reaction involving carbohalide, alkene and amine has been developed, leading to valuable fluoroalkyl-containing amines. A sole inexpensive CuCl is used as the photo- and coupling catalyst. A broad array of substrates are capable coupling partners. The diverse method is compatible with a broad range of functional groups and can be further applied to the

A new and general method for the synthesis of β-azidosulfonates has been achieved through Cu(I)-mediated radical oxidative sulfonylation–azidation of alkenes with sodium sulfinates. Under identical conditions, azido fluoroalkyated products could be readily obtained instead using CF3SO2Na or CHF2SO2Na as reagents. The starting materials of sulfinate compounds, alkenes, and azidotrimethylsilane are stable
通过Cu(I)介导的自由基与亚磺酸钠的烯烃氧化合磺化反应,已经获得了一种合成β-叠氮基磺酸盐的新的通用方法。在相同条件下,使用CF 3 SO 2 Na或CHF 2 SO 2 Na作为试剂,可以轻松获得叠氮基氟代烷基化产物。亚磺酸盐化合物,烯烃和叠氮基三甲基硅烷的起始原料是稳定且便宜的。该方法可以轻松地用于大规模制备。

tolerance, provides a direct and atom-economic approach for the synthesis of valuable β-amino sulfone derivatives as a single regioisomer. In addition to terminal alkenes, internal alkenes participate in this reaction with high diastereoselectivity. N-Sulfonyl ketimines with aryl or alkyl substituents were found to be compatible with this reaction condition. This method could be applied in the late-stage
