Vinyl triflimides are a new compound class with unknown reactivity. A computational anal. identified homolytic cleavage of the N-Tf bond induced by triplet-triplet energy transfer (EnT) as a highly interesting reaction type that might be accessible. A combination of exptl. and mechanistic work verified this hypothesis and proved the generated radicals to be amenable to radical-radical coupling. Thereby, vinyl triflimides H2C:C(Ar)NTf2 (Ar = Ph, 4-BrC6H4, 2-thienyl, etc.) were transformed into a range of α-quaternary, β-trifluoromethylated amines ArC(R)(NHTf)CH2CF3 (R = Me, Et, CN, Ph, etc.) in a 1,2-difunctionalization reaction with no need for external CF3 reagents. In the experiment, the researchers used many compounds, for example, 2-Ethynylthiophene (cas: 4298-52-6HPLC of Formula: 4298-52-6).
2-Ethynylthiophene (cas: 4298-52-6) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.HPLC of Formula: 4298-52-6
