Visible-light-induced [4 + 2] cycloaddition of pentafulvenes by organic photoredox catalysis

We have developed thioxanthylium photoredox catalyzed [4 + 2] cycloaddition of pentafulvenes at room temperature under green light irradiation, which affords tetrahydrocyclopenta[b]chromenes with high regioselectivities. The present reaction provides a sustainable approach to carry out the cycloaddition of pentafulvenes without the use of transition metal catalysts or high-temperature conditions. This procedure enables a mild and straightforward access to 1,3a,9,9a-tetrahydrocyclopenta[b]chromenes. The quantum yield of the reaction (Φ = 0.15) indicates that the reaction would mainly proceed via photocatalytic pathways.

An improved pathway to 6,6-disubstituted fulvenes

Pentafulvenes with alkyl and/or aryl substituents at the exocyclic position are formed rapidly in high yields through reaction of crystalline sodium cyclopentadienide directly with the appropriate ketones.

Cs-symmetric hafnocene complexes for synthesis of syndiotactic polypropene

Three new C s-symmetric ansa-hafnocene complexes such as dichloro[η10-2,4-cyclopentadienyl-1-ylidenebis (4-methyldiphenyl-methylen)[2,7-bis(1,1-di-methylethyl)-9H-fluorene-9- ylidene]]hafnium (2) were synthesized which produce partiell syndiotactic polypropylenes with very high molecular weights. The influence of the methyl and methoxy substitution in the bridge was studied on the activity, tacticity, and molar mass. The hafnocene-MAO catalysts (1-4) were active up to polymerisation temperatures of 90 °C and produces 55 000 kg polymer in 1 h by 1 mol of hafnocene. The molecular weight of the obtained elastic polypropylene reaches 2.2 million g mol-1.

Isolation and Reaction of Selenobenzophenones

4,4'-Dimethoxy- and 4,4'-dimethylselenobenzophenones could be isolated in moderate yields by the reaction of the corresponding ylides with selenium.Their spectral data are described.The oxidation of these compounds with mCPBA afforded the corresponding benzophenones in good yields.Attempted isolation of unsubstituted selenobenzophenone afforded only its dimer.

PREPARATION OF 6,6-DIARYLFULVENE COMPLEXES OF RHODIUM(I) AND THEIR REACTION WITH DIOXYGEN

Complexes (1+) react with 6,6-diarylfulvenes C5H4C(C6H4X-4)2 to yield products C5H4C(C6H4X-4)2L2>(1+) in which the fulvene is bound to the metal through the five-membered ring.Corresponding reactions with (1+) yield complexesC5H4C(C6H4X-4)22>(1+) containing two fulvene ligands.Atmospheric oxidation of these complexes results in the linking of the exocyclic carbon atoms in the two fulvene ligands by a peroxide bridge.If the initial attack by O2 is on the metal, the subsequent rearrangement may be viewed either as a transfer of singlet oxygen from metal to ligands or as a nucleophilic attack by peroxide on the (probably somewhat positively charged) exocyclic carbon atoms of the fulvene ligands.
