A simple base-mediated synthesis of diverse substituted ring-fluorinated 4H-pyrans (monofluorinated 4H-pyrans) from trifluoromethylated alkenes and 1,3-dicarbonyl compounds was developed.
A simple base-mediated tandem SN2'/SNV reaction of readily available -trifluoromethyl-, -unsaturated carbonylcompounds with N-tosylated 2-aminomalonates was developed, which provide an efficient access to functionalized tetrasubstituted 2-fluoro-2-pyrrolines in good to...

Four unprecedented base-catalyzed/mediated nucleophilic additions of TMSCN to α-(trifluoromethyl)styrenes and 2-trifluoromethyl enynes were developed. The reaction proceeded smoothly at room temperature under mild and transition-metal-free conditions without affecting the trifluoromethyl group and afforded the corresponding CF3-containing alkyl, alkynyl, and butadienyl nitriles in moderate to excellent
