A widely studied example of this kind is the synthesis of methyl isobutyl ketone (MIBK, used as a solvent for inks and lacquers) from acetone. The former was previously prepared from the latter through a catalytic three-step process base-catalysed production of 4-hydroxy-4-methylpentan-2-one, acid dehydration into mesityloxide (MO), then hydrogenation of MO on a Pd catalyst. Since acetone aldolization occurs through acid catalysis as shown over a H-MFI zeolite at 433 K (MO is the main reaction product, the aldolization product being rapidly dehy-drated[5]), it is possible, by associating with the acid catalyst a hydrogenation phase,... 

Recently, strikingly new results were obtained with a biopolymer, in which a natural wool carrier combined with PdCb in EtOH to form catalytic complexes (Yin et al. These catalysts hydrogenated diacetone alcohol (4-hydroxy-4-methylpentan-2-one) into (R)-2-methylpentan-2,4-diol and 3-methylbutan-2-one into (R)-3-methylbutan-2-ol (Scheme 3.9.) with ee s of 73% and 100%, respectively. These catalysts could be used repeatedly without decreasing enantioselectivity.
