The heat is on : In the first instance of thermal reactivity of the terminal borylenes [(OC) 5 MBN(SiMe 3 ) 2 ] (M=Cr, W), the new heterodinuclear complexes [(OC) 4 M(μ‐CO){μ‐BN(SiMe 3 ) 2 }Pd(PCy 3 )] (see structure; M=Cr) are synthesized. The compounds feature a semibridging borylene ligand and, by virtue of the dative PdB bonding interaction, represent the only examples of terminal borylene species stabilized by a transition‐metal base.
