Saidalimu, Ibrayim; Guo, Ming; Tokunaga, Etsuko; Shibata, Norio published an article in 2016, the title of the article was Direct Fluoro-aminosulfenylation of Active Methylenes by Dialkylaminosulfur Trifluorides under Catalyst-Free Conditions.SDS of cas: 2510-01-2 And the article contains the following content:
The direct fluoro-aminosulfenylation of active methylene compounds, e.g., 2-(2,3-dihydro-1H-inden-1-ylidene)malononitrile by diethylaminosulfur trifluoride and its derivatives F3SR (R = dimethylamino, diethylamino, bis(2-methoxyethyl)amino, morpholino) has been disclosed. A variety of α-fluorinated α-sulfenamides with a tetrasubstituted carbon center, e.g., I were synthesized from active methylene compounds under mild reaction conditions. This direct fluoro-aminosulfenylation reaction occurs very smoothly under metal-free and base-free conditions. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).SDS of cas: 2510-01-2
