Abstract
The development of efficient C-C bond-forming reactions remains an important objective in organic chemistry. These reactions are fundamental tools for building complex molecules for diverse applications. Among the various strategies available, radical processes promoted by group IV metals—particularly Ti and its titanocene-type complexes—have shown remarkable versatility and utility in organic synthesis. However, closely related zirconium analogues have historically received less attention and have shown a more limited reactivity profile. Thus, zirconium and its zirconocene-type derivatives have often been regarded as the “ugly duckling” of group IV metal-promoted radical chemistry. Yet recent advances indicate that this “ugly duckling” is beginning to reveal its synthetic potential. In this review, we highlight the main synthetic applications of zirconocene(III) complexes and compare…
