[(OC)5Cr=BSi(SiMe3)3]: A Terminal Borylene Complex with an Electronically Unsaturated Boron Atom

[(OC)5Cr=BSi(SiMe3)3]: A Terminal Borylene Complex with an Electronically Unsaturated Boron Atom

An extremely low‐field shifted 11B NMR signal at δ=204.3 and a very short Cr−B distance of 187.8 pm characterize the title compound [(OC)5Cr=B−Si(SiMe3)3] (see structure), which is the first borylene complex in which the boron atom is both coordinatively and electronically unsaturated.
