[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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
