Silver-catalyzed C-H trifluoromethylation of arenes using trifluoroacetic acid as the trifluoromethylating reagent.
TL;DR: This reaction not only provides a new protocol for aryl C-H trifluoromethylation, but the generation of CF3· from TFA may prove useful in other contexts and could potentially be extended to other triffluorometHylation reactions.

Reduction of carboxylic acids into alcohols using NaBH4 in the presence of catechol and/or CF3COOH
TL;DR: In this article, the reaction of aliphatic carboxylic acids (1 eq) using NaBH4 (2 eq) and catechol ( 2 eq) in THF at 25°C gives the corresponding alcohols in 47-49% yield besides the unreacted carboxyl acids.
