Abstract
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.
Claims16
A method for preparing a compound of formula I:
- the method comprising
- forming a first reaction mixture comprising a carbonyl derivatizing agent, an acid, and a compound of formula IIa
- under conditions sufficient to form a compound of formula IIb:
- forming a reaction mixture comprising a catalyst, a hydrogen source, and the compound of formula IIb,
- under conditions sufficient to form the compound of formula I;
- wherein
- R1 and R2 are independently C1-18 alkyl;
- R1a is selected from the group consisting of H and C1-17 alkyl;
