Ketones from oxidation of alcohols

There are several examples where I-LLPTC has been used to synthesize acid anhydrides, by means of a substitution reaction, and ketones from oxidation of alcohols [37-40]. The reaction of an acid chloride (RX) with the carboylate ions (M R catalyzed by PNO is to proceed through an intermediate l-(acyloxy)pyridinium chloride formed in the organic phase. PNO and Af,A -dimethylaminopyridine (DMAP) are widely used as inverse PT catalysts. The formation of hippuric acid was conducted in the presence of 4-dimethy-laminopyridine as inverse PT catalyst [41]. 

Production of aldehydes and ketones from oxidation of alcohols is a fundamental chemical transformation in industry. Using Pd nanoparticles in a poly(ethylene glycol) (PEG) matrix as the catalyst (Scheme 13.10) [63], the oxidations of alcohols are highly efficient in SCCO2 at mild conditions. The selectivity of 3-methyl-2-butene-l-al was above 99% at quantitative conversion of 3-methyl-2-butene-l-ol, and the over-oxidation was not considerable. This method is suitable for a wide variety of alcohols with high selectivity and efficiency.
