Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

open access: yesChemistry – A European Journal, EarlyView.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...
