| titleOfInvention | Method for preparing 1-propenyl or bis (1-propenyl) or allyl- (1-propenyl) compounds |
| abstract | The subject of the invention is a method for obtaining 1-propenyl compounds of the type QCH=CHCH3 or bis(1-propenyl) compounds of the type CH3CH=CH-A-CH=CHCH3 or allyl-(1-propenyl) compounds of the type CH2=CHCH2-X-CH=CHCH3, in in which an allyl compound of the type QCH2CH=CH2 or bis(allyl) of the type CH2=CHCH2-A-CH2CH=CH2 or bis(allyl) of the type CH2=CHCH2-X-CH2CH=CH2, respectively, is subject to isomerization catalyzed by a catalytic system consisting of a strong base in the form of sodium alkoxide or potassium alkoxide and 15-crown-5 for sodium alkoxides or 18-crown-6 for potassium alkoxides. Isomerization reactions are carried out in an ultrasound field with a frequency of 10 to 100 kHz and a power of 100 to 1000 W, at a temperature of -20 to +80°C, in a solvent such as a dialkyl or cyclic ether, dichloromethane, dimethoxymethane or solvent-free. After isomerization is complete, the product is isolated by extraction with water or brine and organic solvents. Thanks to the use of ultrasonics, the reaction time is at least 10 times shorter compared to classical heating, and additionally, it is not required to use a stirrer. Crown ethers and solvents are regenerated and recycled. |
