An examination of the α-arylation of a number of
ketones and their enolate salts by p-methoxyphenyllead
triacetate provides further evidence for a very marked
selectivity in the arylation reaction. It is found that the
reaction proceeds well at tertiary α-carbons and at
secondary centres activated by the presence of a phenyl group,
but fails where the secondary centre is unactivated and at
primary α-carbons.
