of aromatic iodides
was achieved with TMSCF3 in the presence of trimethylborate.
The Lewis acid was used to anchor the in situ generated trifluoromethyl
anion and suppress its rapid decomposition. Broad applicability of
the new trifluoromethylating reaction was demonstrated in the functionalization
of different aromatic and heteroaromatic iodides.
