Isocorannulenofuran: A Versatile Building Block for the Synthesis of Large Buckybowls
摘要:
Isocorannulenofuran, synthesized in two steps from accessible bromocorannulene, gives Diels-Alder adducts with benzynes which can be deoxygenated to produce large polycyclic aromatic hydrocarbons (PAHs) combining the bowl-shaped corannulene subunit with planar fragments.
2-Trimethylsilylcorannulenyl Trifluoromethanesulfonate: An Efficient Precursor for 1,2-Didehydrocorannulene
摘要:
2-Trimethylsilylcorannulenyl trifluoromethanesulfonate, prepared from bromocorannulene, provides a means for generating of 1,2-didehydrocorannulene (corannulyne) under very mild conditions as demonstrated by the high-yield formation of its adducts with dienes.

[GRAPHICS]Treatment of bromocorannulene with NaNH2/tBuOK in THF in the presence of furans or amines leads to formation of addition products in good yields, presumably through formation of 1,2-didehydrocorannulene (corannulyne). HUT calculations predict that corannulyne exists as a bowl-shaped entity and that the didehydrogenation energy of corannulene is slightly lower than that of benzene.
