- W26709852 abstract "The mechanism of the formation of perylene in the presence of H-donor solvents and d{sub 10}-pyrine was studied. Pyrene has been shown to shuttle hydrogen atoms in coal liquefaction studies. Two H-donors, fluorene and 9,10-dihydrophenanthrene were reacted with d{sub 10}-pyrine and 1,1{prime}-binaphthyl in benzene at 470{degree}C for two hours. d{sub 10}-pyrine was synthesized by heating pyrene in a Parr bottle at 270{degree}C for 24 hours in the presence of deuterium choloide in deuterium oxide with a chromium metal catalyst. Mass spectral data showed deuterium incorporated mainly in the reactant binaphthyl and the product perylene probably at the 1, 4, 5 and 8-positions. No deuterium incorporation in the H-donors suggested no shuttling by these compounds while decreased deuterium in the d{sub 10}-pyrine denoted some kind of activity. Significant amounts of deuterium only on perylene and binaphthyl supported the bimolecular reaction between organic molecules." @default.
