Selective oxidation of veratryl alc. (VAlc) to veratraldehyde (VAld) under mild conditions using heterogeneous catalysts is advantageous for industrial applications. In the present study, newly developed SBA-15 supported copper oxide catalyst designated as CuO(5,10,15 weight%)/SBA-15 was examined for the selective oxidation of VAlc to VAld using tert-Bu hydroperoxide (TBHP) as an oxidant between 40 and 100°C. CuO(10 weight%)/SBA-15 showed high conversion (82.5%) compared to others by forming VAld with 100% selectivity. We examined its selective oxidising power using a substrate possessing both the primary and secondary alc. functions, namely propylene glycol (PG). In this substrate, only the secondary alc. group was oxidized to hydroxyacetone (HA). It suggests preferential adsorption of the primary alc. group of PG on the catalyst surface close to the adsorbed TBHP, thus leaving only the secondary alc. group positionally favorable for oxidation In addition, the catalyst effectively oxidized 2-butanol to 2-butanone. So, the catalyst is verified active against both primary and secondary alcs., but when both of them are present on the adjacent carbons of the same compound, only the secondary alc. function is oxidized. So, the present catalyst could have tremendous applications for selective oxidation in organic synthesis. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7Reference of 873-76-7).
(4-Chlorophenyl)methanol (cas: 873-76-7) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Reference of 873-76-7
