We initiated our study by using benzyl isothiocyanate 1a as model substrate in the presence of three equivalent of silver fluoride (Table ). We found that the formed nucleophilic amine was able to react with the electrophilic Munavalli's 23 Ntrifluoromethylthiophthalimide 2a in MeCN at room temperature delivering the desired product 3a in 50% yield (Table ). This encouraging result decided us to further investigate parameters that could enhance the reaction outcome. We first studied the impact of the solvent on the formation of the desired product. THF and 1,4-dioxane as well as DCM were not suitable for the formation of 3a (Table &). Lower yields were obtained when using DMSO and DMF, 30 % and 40 % respectively (Table and).
