Rings, rings, rings: A Friedel-Crafts intramolecular arylation for the synthesis of polycyclic aromatic hydrocarbons from aryl triazenes has been achieved. Polycyclic aromatic compounds consisting of five-, six-, and seven-membered rings can be prepared using this method. Copyright
Co(salen)-catalyzed tert-butyl hydroperoxide oxidation of tert-butylphenols bearing an unsaturated side chain

Co(salen)-catalyzed oxidation of 2,4- and 2,6-di-tert-butylphenols bearing an unsaturated side chain, with tert-butyl hydroperoxide (TBHP) in CH2Cl2 at rt, results predominantly in the formation of tert-butylperoxylated products. The position of tert-butylperoxylation depends on the nature of the unsaturated side chain: predominantly the ortho position for 4-alkynyl-2,6-di-tert-butylphenols, the side chain for 4-alkenyl-2,6-di-tert-butylphenols, and the para position for 4-cyano- or 4-(1-methoxyimino)alkyl-2,6-di-tert-butylphenols as well as 2-alkynyl-, 2-alkenyl-, and 2-cyano-4,6-di-tert-butylphenols. The ortho tert-butylperoxylated products arise mainly from initially formed para tert-butylperoxylated products, by migration of the tert-butylperoxy group.
Reactions of 1-Oxaspiroocta-5,7-dien-4-ones with Nucleophiles

The 1-oxaspiroocta-5,7-dien-4-ones (6-spiroepoxy-2,4-cyclohexadienones) (7) on reaction with a number of carbon, nitrogen, oxygen and halogen nucleophiles produced a variety of interesting substitution and rearrangement products (8)-(19) in moderate yields.The products derived almost exclusively from initial attack of the nucleophile with either the secondary or quaternary carbon of the epoxy ring and these various modes of reaction of the spirocyclic system are discussed.The formation of ortho-substituted phenols from the 1-oxaspiroocta-5,7-dien-4-ones suggests that the latter structures may be regarded as polarity-reversed masked phenols.Tropolones, products of a possible ring-expansion reaction, were not observed in any of the reactions investigated.
