摘要: The present invention provides methods for preparing a C6-C10 alkane, and mixture thereof. The methods include forming a reaction mixture containing an angelica lactone dimer, a catalyst, and a hydrogen source under conditions sufficient to reduce the angelica lactone dimer, thereby preparing the alkane. The methods can be used to prepare branched alkanes useful for fuels. Methods for preparing an angelica lactone, methods for preparing an angelica lactone dimer, and methods for reducing a lactone to an alkane are also described.

摘要: The invention provides a method for preparing a 2,5-dialkyl furan. The method includes forming a reaction mixture containing a catalyst, a hydrogen source, and 2-haloalkylfuran starting material under conditions sufficient to form the 2,5-dialkyl furan. The 2-haloalkylfuran starting material can be derived from biomass, and the 2,5-dialkyl furan product can be used as a biofuel or as a chemical feedstock.

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.
