Diacenaphtho[1,2-c:1′,2′-e]-1,2-dithiin: Synthesis, structure and reactivity

Diacenaphtho[1,2-c:1′,2′-e]-1,2-dithiin 2 was synthesized in 23% yield by the reaction of acenaphthylene with elemental sulfur at 120 °C. This reaction also afforded either diacenaphtho[1,2-b:1′,2′-d]thiophene 1 or diacenaphtho[1,2-b:1′,2′-e]- dihydro[e]-1,4-dithiin 3 depending on the reaction time. Compound 2 was desulfurized and converted to 1 under UV-vis irradiation in a benzene solution. Reaction of 2 with Pt(COD)2 yielded the complex Pt(COD)(C24H12S2) 4 (COD=1,5-cyclooctadiene) by insertion of a Pt(COD) group into the S-S bond of 2. When heated, 4 was desulfurized and converted to 1 by elimination of a (COD)PtS grouping. Compounds 1-4 were characterized crystallographically.

Thiones as reactive intermediates in condensations of diketones with aromatics mediated by tetraphosphorus decasulfide

Phenanthrene-9,10-quinone and P4S10 react with phenols on being heated to give oxathiins, e.g., 9 the dioxin 22, ethers, e.g., 14 arylphenanthrenols, e.g., 10 and furanols, e.g., 17 in addition to sulfides, e.g., 26 and disulfides, e

Facile formation of cyclic polysulfides by a new generation method for diatomic sulfur

A new generation of diatomic sulfur (1) has been achieved in a remarkably simple process by treatment of elemental sulfur with sodium hydride in the presence of phase-transfer catalysts. This facile generation of 1 has been trapped with olefins, diene, and triene to give cycloadducts as the form of cyclic sulfides in high yields.

Novel Syntheses of Decacyclene by Deoxygenating Cyclotrimerisation of Acenaphthenequinone with Zero-valent Titanium or Phosphorus Pentasulfide

Decacyclene (2) was obtained in 15-21% yield by reaction of acenaphthenequinone (6) with bis(η6-biphenyl)titanium(0) (9) in toluene or diglyme at 110°C and in 18% yield by reaction of 6 with phosphorus pentasulfide in boiling toluene. The new reactions are used to attempt the conversion of 3,8-dibromoacenaphthenequinone (7) to 3,4,9,10,15,16-hexabromodecacyclene (3) which is considered to serve as a suitable precursor for the bowl-shaped polycyclic aromatic hydrocarbon C 36H12 (1).
