Lead(IV) tetracarboxylates, prepared from achiral and chiral carboxylic acids, have been shown to undergo metal-metal exchange with phenylboronic acid, and the phenyllead(IV) carboxylates thus generated in situ can be used for Pinhey phenylation reactions

Direct α-vinylations of enolate anions derived from 1,3-dicarbonyl compounds with 4-teri-butyl-1- cyclohexenyl(aryl)iodonium 2 and 1-cyclopentenyl(aryl)iodonium tetrafluoroborates 3 are reported. Frequently, α-phenylations compete with the vinylations in the reaction of 1,3-dicarbonyl compounds with alkenyl(phenyl)iodonium salts 2a and 3a. Use of alkenyl(p-methoxyphenyl)iodonium salts 2b and 3b, however, leads to selective α-vinylation at the expense of the competing arylation of 1,3-dicarbonyl compounds. Use of an efficient aryl radical trap, 1,1-diphenylethylene, inhibits radical-induced decomposition of the alkenyl(aryl)iodonium salts, thereby improving the yields of α-vinylations of enolate anions derived from 1,3-dicarbonyl compounds.
