Abstract
Copper-poly(pyrazolyl)methane complexes have been proven to be highly useful in a
variety of catalytic organic transformations. A multitude of poly(pyrazolyl)methane
ligands have been developed for this effort and are summarized in this work. Their
tailored electronic properties and steric hindrance are easily modified, demonstrating
their diversity and high potential as spectator ligands for copper catalysis. The
listed examples of organic reactions range from cycloadditions to nitrene transfer
and bioinorganic monooxygenase chemistry.
