Abstract

Potassium [1-(tert-butoxycarbonyl)-1H-indol-2-yl]trifluoroborate (1) was used in Suzuki-type coupling reactions. First, the best coupling conditions were assessed using bromobenzene as the electrophile. Then, 1 was successfully coupled with various aryl and hetaryl bromides. Finally, the reactivity of 1 towards coupling partners other than bromide derivatives was evaluated.

Key words

Suzuki coupling - organotrifluoroborates - palladium catalysis - indoles
