abstract |
The catalytic performance of methyltrioxorhenium(VII) (MTO) has been investigated for the first time in the isomerization of a-pinene oxide (PinOx) into campholenic aldehyde (CPA). The high isomerization activity of MTO is coupled with high selectivity to CPA: CPA yield of up to 87% (100% conversion) was obtained by using alpha,alpha,alpha-trifluorotoluene as solvent at 15 degrees C. Catalyst recycling is possible in a relatively simple fashion by using MTO coupled to an appropriate ionic liquid. The catalytic application of MTO in the isomerization of PinOx versus the integrated epoxidation-isomerization process of the conversion of alpha-pinene into CPA is discussed. (C) 2013 Elsevier B.V.
