A Convenient One-Pot Synthesis of Acenaphthenequinones from 1-Acenaphthenones by NBS-DMSO Oxidation

Acenaphthenequinone was obtained in 95percent yield whwn the teaction of 1-acenaphthenone with N-bromosuccinimide was carried uot in dimethyl sulfoxide at room temperature.Under similar conditions, several acenaphthenequinones were prepared from the corresponding 1-acenaphthenones in good yield.

Palladium-catalyzed trimerization of strained cycloalkynes: Synthesis of decacyclene

Palladium-catalyzed cyclotrimerization was applied to three strained cycloalkynes. Pd(PPh3)4 and Pt(PPh3)4-catalyzed cyclotrimerizations of cyclohexyne (2) afforded dodecahydrotriphenylene (3) in 64% and 62% yields, respectively, but subjecting cyclopentyne to the same conditions failed to afford isolable amounts of the cyclotrimer. Finally, decacyclene (15), a putative C60-fullerene precursor, was obtained in 23% yield by Pd2(dba)3-catalyzed cyclotrimerization of acenaphthyne (14).
