Paragraph 0033; 0036; 0063-0127, (2021/03/13)
The invention provides a method for synthesizing styrallyl acetate from acetophenone, which comprises the following steps: reacting acetophenone with ketene under the catalysis of organic acid to obtain styrene acetate, and hydrogenating styrene acetate to obtain styrallyl acetate. The method is novel in synthetic route, the raw materials acetophenone and ketene are cheap and easy to obtain, the synthetic route is short, the yield is high, no equivalent acetic acid byproduct is produced, and the method has an obvious cost advantage.

Herein, we report a protocol for visible-light-mediated radical coupling reactions of α-chloroketones and enol acetates to afford 1,4-dicarbonyl compounds, which are important precursors and intermediates in organic synthesis. The reaction involves photoredox-catalyzed activation of the α-chloroketone upon photoelectron transfer, carbon–chlorine bond cleavage, and coupling of the resulting radical with the carbon–carbon double bond of the enol acetate. This mild protocol has a wide substrate scope and moderate to good yields. (Figure presented.).

We developed a method to synthesize fluorinated 1,4-unsaturated dicarbonyl compounds via photoredox catalyzed radical addition process. Commercially available ethyl bromodifluoroacetate (BrCF2CO2Et) as fluoroalkyl source, the corresponding fluoro-containing dicarbonyl compounds could be obtained in moderate to good yields.
