Cu(OTf)2/NBS-Mediated Tandem Reaction of
1‑Cinnamyl Alcohol‑o‑Carboranes
via Ring Opening of Oxetane with Arenes: An Alternative Approach for
the Synthesis of C‑Alkenyl‑o‑Carboranes

The Cu(OTf)2/NBS-mediated tandem reaction
of 1-cinnamyl
alcohol-o-carboranes for the synthesis of C-alkenyl-o-carboranes has been developed. Mechanism studies demonstrated
that the Cu(OTf)2-promoted ring opening of oxetane with
electron-rich arenes as soft nucleophiles was involved and was the
key step for the transformation. This work provided an alternative
strategy for the synthesis of C-alkenyl-o-carboranes,
which has an important reference for the synthesis of o-carborane derivatives with diversity.
