Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4...
sulfuric acid and phosphoric add; organic sulfonic acids, such as methanesulfonic acid and p-toluenesulfonic acid; amphoteric catalysts, more particularly compounds of titanium, tin(IV) compounds, or zirconium compounds, such as tetraalkoxytitaniums, e.g., tetrabutoxytitanium, and tin(IV) oxide. ...
