摘要:
A series of heterocyclic triaryl methanols were prepared and reacted with enol silyl ethers in the presence of ZnCl2. This reaction gave a variety of functionalized heterocyclic products. A mechanism is proposed involving formation triaryl carbocation electrophiles with delocalization of positive charge to positions in the heterocyclic rings. Nucleophilic attack then occurs at a ring position of the heterocycle. & COPY; 2023 Published by Elsevier Ltd.
