Reductive Bergman-type cyclizations of cross-conjugated enediynes to fulvene and fulvalene anions: The role of the substituent

Various cross-conjugated enediynes undergo "Bergman-type" cycloaromatizations upon reduction with potassium metal, generating anions of fulvenes and fulvalene derivatives. This new anionic cyclization is considerably more facile than the classic Bergman cyclization with linear enediynes, creating highly reactive diradicals at -78 °C. Not all cross-conjugated enediynes yield cyclized dianions upon reduction; some give uncyclized, Y-shaped, cross-conjugated dianions, while others apparently yield radical-anions that either dimerize or persist as monomers. One system yields both a cyclized and an uncyclized dianion. The substituents are thus shown to be a critical factor in determining the outcome of the reduction. Cyclization occurs within a specific "window of opportunity" that is governed by the substituents.

TETRACATIONIC CYCLOPHANES AND THEIR USE IN THE SEQUESTRATION OF POLYAROMATIC HYDROCARBONS BY WAY OF COMPLEXATION

Novel tetracationic cyclophanes incorporating π-electron poor organic compounds into their ring structures, as well as methods of making the cyclophanes, are provided. The cyclophanes are able to form electron donor-acceptor complexes with a variety of polyaromatic hydrocarbons (PAHs) ranging in size, shape, and electron density. Also provided are methods of using the cyclophanes in the sequestration of PAHs in liquid or gaseous samples, the separation of PAHs from liquid or gaseous samples, the detection of PAHs in liquid samples, and the exfoliation of graphene via pseudopolyrotaxane formation.

Assembly of organosilver coordination frameworks with aromatic ligands bearing a terminal enediyne group

In a series of five silver(I) complexes synthesized with (2-ethynylbut-1-en-3-yne-1,1-diyl)dibenzene (H2L1) and 9-(penta-1,4-diyn-3-ylidene)-9H-fluorene (H2L2), each resulting ethynide ligand is invariably inserted into a Agn/s
