Transition hydrogenation of 4-fluorocinnamic acid
The initial state
of 4-fluorocinnamic acid has the structure of an ethylenically bonded and a carboxyl group. At the beginning, it exists as a conjugated system, with active ethylenically bonds, and can cope with many changes. It is an important starting material in the field of organic synthesis, and often uses its ethylenically reactive bonds to build a multi-component organic structure.
Method of transfer hydrogenation
Transfer hydrogenation
The method of transferring hydrogenation is not using hydrogen as a hydrogen source, but by means of a hydrogen-containing donor. In this case, choose a suitable hydrogen donor, such as isopropanol. Supported by a specific catalyst, or a metal complex such as ruthenium, rhodium and other metals. This catalyst has high catalytic activity and can activate the hydrogen donor and 4-fluorocinnamic acid, so that the hydrogen transfer reaction between the two can occur smoothly. When the
reaction occurs, the hydrogen donor releases hydrogen atoms under the action of the catalyst, which attack the ethylenic bond of 4-fluorocinnamic acid in the state of an active hydrogen species. The pi bond of the ethylenic bond breaks, combines with the hydrogen atom, and gradually forms the product of hydrogenation. During this process, the catalyst goes through a series of steps such as coordination, activation, and hydrogen transfer, which drives the reaction forward efficiently.
