[reaction: see text] We have successfully prepared potassium azidoalkyltrifluoroborates from the corresponding halogen compounds in 94-98% yields through a nucleophilic substitution reaction with NaN(3). In the presence of various alkynes and Cu(I) as a catalyst, these azidotrifluoroborates easily formed 1,4-disubstituted

Potassium Organotrifluoroborates

These bench stable Potassium Organotrifluoroborates are useful for Suzuki-Miyaura cross-coupling reactions and have also been used for a variety of other C-C bond forming reactions. Importantly, these reagents are compatible with a wide range of functional groups and are stable to many commonly used and harsh reaction conditions.
