摘要: Provided herein are methods for preparing alkylfurans, such as 2,5-dialkylfurans and 2-alkylfurans. Furfural or 5-alkylfurfural can be reacted with aniline or diaminobenzene, or derivatives thereof, to form the corresponding imine, which can be reduced to form alkylfurans and to regenerate the aniline or diaminobenzene, or derivatives thereof. The alkylfuran may be, for example, 2,5-dimethylfuran or 2-methylfuran.
摘要翻译: 本文提供了用于制备烷基呋喃的方法,例如2,5-二烷基呋喃和2-烷基呋喃。 糠醛或5-烷基糠醛可以与苯胺或二氨基苯或其衍生物反应形成相应的亚胺,其可被还原形成烷基呋喃并再生成苯胺或二氨基苯或其衍生物。 烷基呋喃可以是例如2,5-二甲基呋喃或2-甲基呋喃。
