Stepwise Intermetal Borylene Transfer: Synthesis and Structure of Mono- and Dinuclear Cobalt-Borylene Complexes

Step by step: Stepwise transmetalation of the borylene ligand BN(SiMe3)2 from [(OC)5WBN(SiMe3)2] to [(η5‐C5H5)Co(CO)2] gives access to the first mono‐ and dinuclear cobalt borylene species and provides convincing evidence that the intermetal borylene transfer proceeds by an associative process wit...

Description
Summary:Step by step: Stepwise transmetalation of the borylene ligand BN(SiMe3)2 from [(OC)5WBN(SiMe3)2] to [(η5‐C5H5)Co(CO)2] gives access to the first mono‐ and dinuclear cobalt borylene species and provides convincing evidence that the intermetal borylene transfer proceeds by an associative process with a heterodimetallic intermediate (see structure) without generation of an intermediate free borylene species.
