Efficient copper-catalyzedtrifluoromethylation 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.

The rate-retarding effect of ?-trifluoromethyl group observed in the solvolysis of 1-aryl-1-(trifluoromethyl)ethyltosylates is so profound that a very large negative α+ value, −8.82, is resulted and the 1-phenyl derivative becomes even less reactive than benzyl tosylate.

A new strategy towards [18F]trifluoromethyl-containing compounds is developed. [18F]trifluoromethane is synthesised in a fast and efficient manner and subsequently used in the reaction with aldehydes and ketones forming [18F]trifluoromethyl carbinols in good yields.

Fluoride ion induced cross-coupling reaction of organic halides with trifluoromethyltrialkylsilanes takes place in the presence of Cu(I) salts under mild reaction conditions to give the corresponding trifluoromethylated products in high yields.
