Direct Synthesis of γ-Substituted Phthalides Via ortho-Aryl Benzoic Acid Mediated Benzyl Radical Cyclization
Mahmoodi,Salehpour
, p. 875 - 878 (2007/10/03)
Direct synthesis of γ-substituted phthalids from related ortho-aryl benzoic acids with 48-85% yield are covered. The direct oxidation in the presence of peroxydisulphate-copper (II) chloride in aqueous medium was applied. The reaction is highly regioselective and leads exclusively to γ-butyrolactone, through very stable benzylic radical intermediate.
Direct synthesis of γ-substituted phthalides by cyclization of benzyl radicals generated from o-(arylmethyl)benzoic acids
Mahmoodi,Salehpour
, p. 1760 - 1763 (2007/10/03)
Direct oxidation of o-(arylmethyl)benzoic acids with sodium peroxysulfate-copper(II) chloride in water yields γ-substituted phthalides. The reaction is highly regioselective, and the corresponding γ-butyro-lactones are the only products formed through intermediate stable arylmethyl radicals.
Synthesis of Nuclear Monobromobenzanthracenes
Newman, Melvin S.,Hussain, N. Shoukath

The syntheses of 2-bromo-, 5-bromo-, 10-bromo-, and 11-bromo-7-methylbenzanthracenes, of 5-bromo- and 7-bromo-12-methylbenzanthracenes, and 4-bromo- and 9-bromo-7,12-dimethylbenzanthracenes are described.Bromination of 12-methylbenzanthracene
