Abstract

Although aryldiazonium tetrafluoroborates have been well established as coupling partners in Pd-catalyzed reactions, there are some drawbacks. First, aryldiazonium tetrafluoroborates are generally unstable and only few of them are commercially available. Therefore, they should be newly prepared before use. However, the procedure for the preparation of aryldiazonium tetrafluoroborates is hazardous and tedious due to the use of fluoroboric acid and recrystallization in ...
