Journal ArticleDOI
Synthetic Methods for Compounds Having CF3–S Units on Carbon by Trifluoromethylation, Trifluoromethylthiolation, Triflylation, and Related Reactions
Journal ArticleDOI
Synthesis of Indole and Biindolyl Triflones: Trifluoromethanesulfonylation of Indoles with Tf2O/TTBP (2,4,6-tri-tert-butylpyridine) System
TL;DR: A convenient synthesis of indole triflones is reported and an environmentally friendly solvent, Solkane 365/227, can be substituted for this process without any loss of efficiency.
Journal ArticleDOI
S‐((Phenylsulfonyl)difluoromethyl)thiophenium Salts: Carbon‐Selective Electrophilic Difluoromethylation of β‐Ketoesters, β‐Diketones, and Dicyanoalkylidenes
TL;DR: Thiophenium salts were found to be efficient as electrophilic difluoromehtylating reagents for introduction of a CF2 H group to sp(3) -hybridized carbon nucleophiles such as of β-ketoesters and dicyanoalkylidenes.
Journal ArticleDOI
Regioselective Synthesis of Heteroaryl Triflones by LDA (Lithium Diisopropylamide)-Mediated Anionic Thia-Fries Rearrangement
TL;DR: Novel heteroaryl triflones including oxindole, pyrazolone, pyridine, and quinoline derivatives have been regioselectively synthesized by LDA-mediated thia-Fries rearrangement for the first time.
Journal ArticleDOI
Selective O-Difluoromethylation of 1,3-Diones by Bromodifluoromethylating Reagents
TL;DR: The regioselective O-difluoromethylation of 1,3-diones was achieved via in situ generation of diffluorocarbene from bromodifluorsitting reagents in the presence of an organic base.
