1-Borabarrelene derivatives via Diels-Alder additions to borabenzenes.
[reaction: see text] Borabenzene reacts with strong dienophiles such as dimethylacetylenedicarboxylate or benzyne to afford substituted borabarrelenes and borabenzobarrelene, respectively. The resultant Diels-Alder adducts display high stability due to increased Lewis acidity at boron.
