Pyrazole-4-boronic acid pinacol ester
CAS 269410-08-4
The boron is not usually meant to stay. In this pyrazole building block, Bpin is a temporary handle for constructing a permanent carbon-carbon bond.
CAS 269410-08-4 stores a 4-pyrazolyl fragment in a stable Bpin form. Suzuki coupling trades the C-B bond for a new C-C connection.
