“…The C–H bonds on the 9 and 10 positions of 9,10-dihydroanthracene were sufficiently weak to initiate the reaction, and the conversion of α-methylstyrene and 9,10-dihydroanthracene proceeded even in the absence of asphaltenes, which is consistent with a previous report . The dominant product in the methanol extract was the dimerization product of α-methylstyrene and 9,10-dihydroanthracene, and the selectivity to cumene was only 15%, which was contrary to what was anticipated from literature, which reported the near complete selectivity to cumene, albeit with 6 H -benzo­[cd]­pyrene also present in the reaction mixture.…”

“…In these experiments the industrial asphaltenes feed was mixed with selected model compounds, and some model compound mixtures were studied on their own. Diphenylether was employed as insert solvent, subsequent to a report that it was not degraded during reaction of a mixture of α-methylstyrene, 6 H -benzo­[cd]­pyrene, and 9,10-dihydroanthracene in diphenylether at 250 °C . A list of the experiments that were performed is shown in Table .…”

“…The use of less sterically hindered nucleophiles such as hexynyl lithium and reduction of 4 with LiAlH 4 /AlCl 3 led to the recovery of the starting material. 26 Nevertheless, this unexpected 1,4addition provided the possibility for the substitution at 5-and 7-positions, which is of interest for functionalization in the future. OR1 and OR2 appeared dark green in color in solution and black in color as solids, and the structures were unambiguously determined by X-ray crystallography (vide infra), ESI-MS and MALDI-TOF-MS.…”

“…The synthesis of 6-position-protected olympicenyl radical derivative OR1 was realized by treatment of 6 H -benzo­[ cd ]­pyren-6-one ( 1 ) with lithiated triisopropylsilyl (TIPS) acetylene, followed by reduction with H 2 SnCl 4 . To further functionalize the periphery, we conducted Ir-catalyzed borylation reaction which selectively activated 4- and 8-positions with the least steric hindrance .…”
