摘要
p-Toluenesulfonyl radical can be generated from sodium p-toluenesulfinate in aqueous acetic acid or formic acid. Sulfonyl radical mediating reaction of 5-aryl substituted alkenes with sodium p-toluenesulfinate/copper(II) acetate gave p-toluenesulfonylmethyl substituted naphthalene and isoquinoline derivatives. This reaction proceeded much raster in aqueous formic acid than in aqueous acetic acid. The cyclization mode (Ar-2-6 vs Ar-1-5) of the 5-phenyl-1-butly radical is strongly dependent on the geometry of the tether of the radical intermediate. (C) 1999 Elsevier Science Ltd.
