Oxyfunctionalization of alkanes with hydrogen peroxide on titanium silicalite

A study that shows that titanium silicalite, a microporous crystalline Ti-silica, is able to activate secondary and tertiary carbon atoms in alkanes, so that they may be oxidized to alcohols and subsequently to ketones using aqueous H2O2 is presented. The catalyst has low regioselectivity for alcoho...

Zusammenfassung:	A study that shows that titanium silicalite, a microporous crystalline Ti-silica, is able to activate secondary and tertiary carbon atoms in alkanes, so that they may be oxidized to alcohols and subsequently to ketones using aqueous H2O2 is presented. The catalyst has low regioselectivity for alcohol formation but high reactant selectivity in the formation of ketones.
