摘要

A simple, atom economical, highly efficient and green protocol has been developed for the SN1-type substitutions of 9H-xanthen-9-ol with indoles or other nucleophiles (such as diketone and pyrrole). This approach provides the substitution products in high or excellent yields in the BmimBF4 media at room temperature.
