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.

甲氧基苯基三
乙酸铅的α-芳基化反应的研究提供了进一步的证据,表明该芳基化反应具有显著的选择性。研究发现,该反应在三级α-碳位和受到苯基取代所激活的二级中心进行良好,但在未被激活的二级中心和一级α-碳位时则失败。
