Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), is researched, Molecular C30H24F12N6P2Ru, CAS is 60804-74-2, about C-H Acyloxylation of Polycyclic Aromatic Hydrocarbons.Product Details of 60804-74-2.
The C-H acyloxylation of polycyclic aromatic hydrocarbons (PAHs) such as fluoranthene, 3,4-benzopyrene, benz[a]anthracene, etc. is described. This reaction constructs aryl acyloxylate scaffolds ArOC(O)R (Ar = fluoranthen-3-yl, anthracen-9-yl, 10-bromoanthracen-9-yl, etc.; R = Me, 2-naphthyl, 4-trifluoromethylphenyl, 2,3-dihydro-1H-inden-2-yl, etc.) from PAHs with equimolar hypervalent iodine compounds PhI(OC(O)R)2 under mild reaction conditions. Interestingly, the blue light irradiation accelerated this transformation. Addnl., the synthesis of structurally new sym. and unsym. diaroyloxylated fluoranthenes I (R = 2-iodophenyl, 4-bromophenyl, 4-trifluoromethylphenyl, 3-trifluoromethylphenyl, 2-trifluoromethylphenyl) was accomplished with a ruthenium photoredox catalyst.
