DOI: 10.1002/ejoc.201701752
Abstract: Isomeric fluorinated α‐bromoenones react with dinucleophilic β‐mercaptoalcohols in CH2Cl2 at room temperature in the presence of Et3N in a multistep process. Depending on the position of the CF3 group, different O,S‐heterocycles or non‐cyclic products were… read more here.

Abstract: Abstract We investigated the palladium-catalyzed [2 + 2 + 1] cycloaddition of aryl- and trifluoromethyl-group-substituted internal alkynes and carbon monoxide, and revealed that the PdBr2 effectively catalyzed the intended reaction. The PdBr2-catalyzed reaction smoothly proceeded and provided aryl- and… read more here.

DOI: 10.1021/acsomega.9b03936
Abstract: A combination of ruthenium catalyst with silver salt and copper salt was proved to be a highly efficient protocol for the direct addition reaction of benzoic acids with unsymmetrical trifluoromethylated internal alkynes. Diverse trifluoromethyl group-substituted… read more here.
