Nucleophilic routes to selectively fluorinated aromatic compounds starting
from cheap and readily available nitroaromatics are reviewed. Me3SiCF3, in
conjunction with a fluoride, can be used as either a fluorinating or triflu
oromethylating agent, and is capable of both the trifluoromethyldenitration
and trifluoromethyldecyanation of an aromatic molecule. Nucleophilic trifl
uoromethylthiolation can be achieved using thiophosgene and a fluoride. (C)
