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. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8Recommanded Product: 13669-10-8).
Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Recommanded Product: 13669-10-8
