Direct Annulations toward Phosphorylated Oxindoles: Silver‐Catalyzed Carbon‐Phosphorus Functionalization of Alkenes

Silver-Catalyzed Tandem Radical Cyclization for the Synthesis of 3,3'-Disubstituted Oxindoles

“…尤其, 可供 选择的方法是 N-芳基丙烯酰胺经历自由基环化的过程 来完成 [7] . 就在不久前, 我们课题组运用这种策略在温 和的条件下用银催化分别成功合成了碳磷酰化 [8] 和叠氮 芳基化 [9] 的氧化吲哚(图 1).…”

Electrooxidative CH/PH functionalization as a novel way to synthesize benzo[b]phosphole oxides mediated by catalytic amounts of silver acetate

“…[15][16][17]34,35 It has been found that joint electrochemical oxidation of diphenylphosphine oxide and acetylene in the presence of 0.1 equiv. AgOAc at room temperature leads to the formation of benzo [b]phosphole oxide 3 with mild to high yields (Table 1).…”

“…We proposed that one key step in the investigated catalytic cycle should be AgP(O)Ph 2 oxidation. 16,35 Some contradictions should be noted in the studies of Ag-catalyzed C-H phosphonations.…”

Metal-Free Polychloromethylation/Cyclization ofN-Aryl Acrylamides

“…基于这一策略, 各种金属 催化(如 Ag, Cu, Fe, Mn 等) [3] 和无金属催化 [4] 的新反应相 继被报道. 氯仿(CHCl 3 )和二氯甲烷(CH 2 Cl 2 )是常见的溶剂, 同 时 也 是 很 好 的 多 氯 甲 基 自 由 基 源 , 在 过 氧 苯 甲 酰 (BPO) [5] 、过氧化二异丙苯(DCP) [6] 等引发剂以及光催化 剂作用下 [7] , 能选择性地产生多氯甲基自由基.…”

“…我们设 想以氯仿和二氯甲烷作为多氯甲基自由基源, 将产生的 多氯甲基自由基与 N-芳基丙烯酰胺反应, 通过自由基 加成/环化过程合成多氯甲基取代的 2-吲哚酮类化合物, 从而为官能化吲哚酮化合物的合成提供一种新方法. 3,134.6,129.6,129.4,128.4,128.1,126.3,125.9,122.4,109.8,96.3,60.2,48.2,27.4;HRMS (ESI) 178.9, 140.8, 134.2, 132.7, 124.6, 123.1, 102.7, 95.9, 60.1, 47.7, 30.0, 27 177.8, 145.8, 135.3, 132.9, 125.2, 123.2, 107.9, 95.9, 57.6, 48.6, 26.9, 22.9 5, 146.2, 135.4, 130.9, 125.9, 123.0, 108.1, 69.7, 48.4, 47.9, 26.8, 22.7 …”
