Step by step : Stepwise transmetalation of the borylene ligand BN(SiMe 3 ) 2 from [(OC) 5 WBN(SiMe 3 ) 2 ] to [(η 5 ‐C 5 H 5 )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.
