Functionalization of furfural can be achieved by photocatalytic C−H activation of the aldehyde and coupling to electron-deficient olefins. With (Bu4N)4W10O32 as the photocatalyst, furfural can be added to benzylidene malononitriles, acrylates, itaconic anhydride, maleic anhydride, 2-vinylpyridine and phenyl vinyl sulfone to form the corresponding furanyl ketones in moderate-to-good yields.
糠醛的官能化可以通过醛的光催化CH活化和与缺电子烯烃的偶联来实现。以(Bu 4 N) 4 W 10 O 32为光催化剂,糠醛可与亚苄基丙二腈、丙烯酸酯、衣康酸酐、马来酸酐、2-乙烯基吡啶、苯基乙烯基砜等反应生成相应的呋喃酮。产量。
