Fashionably late: Synthesis and characterization of transition-metal- fluoroborylene complexes

Chemical equation presentation. B and F become BFFs: The last of the neutral first-row main group diatomics, BF, has conspicuously eluded synthetic chemists and their attempts to stabilize it by transition metals. After decades of near misses, two contrasting families of fluoroborylene transition metal complexes have been definitively synthesized by the research groups of Aldridge and Andrews.
