A, p-unsaturated aldehydes selective

The 0-atom donor, lutidine-AT-oxide, has been used with Ru(TMP)(0)2 to catalyze the room temperature oxidation of alcohols to the corresponding aldehydes or ketones in -80% . Thus, under Ar, allyl alcohols were oxidized selectively to a,P-unsaturated aldehydes selectively, and PI1CH2OH to PhCHO Ph(CH2)20H was not oxidized. Cyclohexanol and adamantanol gave the corresponding ketones. The related 2,6-Cl2pyNO system, mentioned in the previous section, catalytically oxidizes cyclohexanol to cyclohexanone. ...
