Key Points

Efficient dehydroborylation of alkenes is achieved using a novel germyl pincer ligand.
Key Ge–Ni complexes were isolated and characterized, providing insights into their catalytic role.
Observational analysis of catalytic mechanisms indicates significant β-H elimination steps in the cycle.
The findings suggest a unique capability of the germyl pincer ligand for enhanced catalytic activity.

Abstract

A recently reported P-GeH2-P germyl pincer ligand has been successfully applied to enable an efficient nickel-catalyzed dehydroborylation of alkenes. Isolation and characterization of key Ge–Ni complexes, combined with mechanistic studies, suggest that these species serve as catalytically relevant precursors. Furthermore, the germyl pincer ligand may exhibit a unique ability to promote the β-H elimination step in the nickel catalytic cycle.
