| titleOfInvention | Method for synthesizing alpha, beta-unsaturated aldehyde without synthesis gas |
| abstract | The invention relates to a method for efficiently synthesizing alpha, beta-unsaturated aldehyde. According to the hydrogen formyl transfer reaction between simple alkyl aldehyde and alkyne, n-butyl aldehyde which is cheap and easy to obtain is used as a donor of hydrogen formyl, and a series of alkyne can be efficiently and quickly converted into alpha, beta-unsaturated aldehyde. Compared with the traditional hydroformylation reaction system, the method does not need to use flammable and explosive synthesis gas, does not need to use a special device to contain the synthesis gas, adopts commercially available catalysts and ligands, has simple and convenient operation, mild conditions and low cost, thoroughly inhibits side reaction products such as saturated aldehyde and alkyne hydrogenation products, has specific chemical selectivity, excellent regioselectivity and stereoselectivity, and has huge application potential. |
