Facile isomerization of silyl enol ethers catalyzed by triflic imide and its application to one-pot isomerization–(2 + 2) cycloaddition

A triflic imide (Tf(2)NH) catalyzed isomerization of kinetically favourable silyl enol ethers into thermodynamically stable ones was developed. We also demonstrated a one-pot catalytic reaction consisting of (2 + 2) cycloaddition and isomerization. In the reaction sequence, Tf(2)NH catalyzes both of the reactions.

Electrocatalytic intermolecular olefin cross-coupling by anodically induced formal [2+2] cycloaddition between enol ethers and alkenes.

Electrochemical reactions have proven to be valuable means for reversing the polarity of alkenes and triggering radical anionor radical cation-based cyclizing reactions. Anodic olefin coupling initiated by oxidation of electronrich olefins can provide powerful tools for achieving intramolecular cyclization reactions and building new ring systems. In this case, several combinations of olefins ca...
