TLDR The process efficiently converts α-pinene oxide to campholenic aldehyde using a special catalyst, achieving high yields quickly.
The study explored the isomerization of α-pinene oxide to campholenic aldehyde using ionic liquid-supported indenyl-molybdenum(II)-bipyridine complexes as catalysts, achieving high yields of 90-94% within 1 minute at 35°C. This surpassed previous catalysts' performance and highlighted the benefits of ionic liquids in catalyst recovery and reuse. The research indicated that ligand modification could enhance catalytic activity and selectivity, with stable recycling performance observed. The efficiency was influenced by the molar ratio of Mo:PinOx, catalyst concentration, and ionic liquid type, with [Ch][NTf2] being particularly effective, while water presence reduced selectivity.
