Single-Electron Transfer Driven Cyanide Sensing: A New Multimodal Approach [作者：AJAYAKUMAR M R; MUKHOPADHYAY PRITAM; YADAV SARITA; GHOSH SUBHASIS,期刊：Organic Letters, 页码：2646-2649 , 文章类型： Article，,卷期：2010年12-11] A new SET-driven reaction-based strategy is reported for sensing of cyanide with indicators having low LUMO levels. The cyanide-specific reaction produces an air-stable radical anion marker and by virtue of its spin, cha... Stereoselective Additions of Thiyl Radicals to Terminal Ynamides [作者：BANERJEE BIPLAB; LITVINOV DMITRY N; KANG JUNGHOON; BETTALE JENNIFER D; CASTLE STEVEN L,期刊：Organic Letters, 页码：2650-2652 , 文章类型： Article，,卷期：2010年12-11] Two complementary sets of conditions for radical additions of thiols to terminal ynamides are described. The use of 1 equiv of thiol affords the cis-beta-thioenamide adducts in rapid fashion (10 min) and good dr, whereas... NHC Catalyzed Transformation of Aromatic Aldehydes to Acids by Carbon Dioxide: An Unexpected Reaction [作者：NAIR VIJAY; VARGHESE VIMAL; PAUL RONY RAJAN; JOSE ANU; SINU C R; MENON RAJEEV S,期刊：Organic Letters, 页码：2653-2655 , 文章类型： Article，,卷期：2010年12-11] A facile NHC-mediated reaction of aromatic aldehydes with carbon dioxide leading to carboxylic acids is described. The present protocol is mechanistically important, and it can serve as a tool for the sequestration of ca...
