PROCESS FOR THE ISOMERISATION OF SUBSTITUTED ALKENES |
| 摘要 |
The invention relates to a process for the isomerization of unsaturated fatty acids or esters or amides thereof, said process comprising reacting:
(a) an unsaturated fatty acid or ester or amide thereof;(b) a source of Pd;(c) a bidentate diphosphine of formula I,;R1R2>P1-R-P2<R3R4 (I)wherein P1 and P2 represent phosphorus atoms; R1, R2, R3 and R4 represent tert-butyl; and wherein R represents an optionally substituted aromatic group spanning P1 and P2;(d) a lower alcohol; and(e) an acid co-catalyst,under conditions for isomerization to take place.;The process is particularly advantageous for the isomerization of substituted alkenes harbouring a hydroxy group when the desired end product has a keto group, such as ricinoleic acid or ester thereof. |

1. A process for the isomerization of unsaturated fatty acids and/or an ester and/or an amide thereof, said process comprising reacting:
(a) an unsaturated fatty acid and/or ester and/or amide thereof; (b) a source of Pd; (c) a bidentate diphosphine of formula I,
R1R2>P1-R-P2<R3R4 (I) wherein P1 and P2 represent phosphorus atoms; R1, R2, R3 and R4 represent tert-butyl; and wherein R represents an optionally substituted aromatic group spanning P1 and P2; (d) a lower alcohol; and (e) an acid co-catalyst, under conditions for isomerization to take place. |
