Abstract
Abstract Boron difluoride (BF 2 ) complexes with asymmetrical N,N’‐bidentate ligands have received increasing attention due to their fascinating properties and broad applications. They are generally constructed in two steps: ligand formation, followed by boron complexation. This review focuses on categorizing these BF 2 complexes based on the key synthetic strategies that have been applied in the ligand formation steps. The post‐functionalization, properties and applications of different types of BF 2 complexes are presented. Their challenges and opportunities are also discussed. This should help the future rational design and synthesis of BF 2 complexes with intriguing properties and practical applications.
