Synthesis of fused arylboronic esters via cobalt(0)-mediated cycloaddition of alkynylboronates with alpha,omega-diynes.
[reaction: see text] Co(2)(CO)(6)-complexed alkynyl pinacolborane derivatives are readily transformed with functional group tolerance into fused arylboronates via the [2 + 2 + 2]cycloaddition to alpha,omega-diynes.
