Graphical Abstract

Diverse reactions of borylene–carbonyl species, including reduction, migration, and complete cleavage of CO, lead to the formation of new types of borylenes, and demonstrate the use of main-group compounds as transition-metal mimics.

Abstract

The borylene–carbonyl moiety in [bis(silylene)B(CO)][WBr(CO)5] shows diverse reactivity. Reduction, migration, and complete cleavage of CO have been observed at the boron center, leading to the formation of new types of borylenes. These reactions not only serve as new methods for the synthesis of various stable borylenes, but also demonstrate that main-group-element compounds can mimic the behavior of transition-metal complexes.
