NOVELTY - Preparation of furan-type compound (I') involves converting furan-type compound (A) in presence of hydrogen, catalyst and reagent(s) chosen from amido group-containing compound (i), urea-type compound (ii) and imidazolidin-2-one-type compound (iii).    USE - Preparation of furan-type compound e.g. 2,5-dimethylfuran and 2-methyl-furan (all claimed) used as biofuel.    DETAILED DESCRIPTION - Preparation of furan-type compound of formula (I') involves converting furan-type compound of formula (A) in presence of hydrogen, catalyst and reagent(s) chosen from amido group-containing compound of formula (i), urea-type compound of formula (ii) and imidazolidin-2-one-type compound of formula (iii).    R'1=mC alkyl;    m=0 or more;    R'2=nC alkyl;    n=1 or more;    R1a=mC alkyl, or -(CH2)mY';    Y'=halo;    R2a=-(CH2)n-1CH(O), -(CH2)nOH or -(CH2)X;    X=halo;    Ra-Rd=H, aliphatic group, aryl or heteroaryl;    or Ra+Rb+N,Rc+Rd+N =cyclic moiety having 3 or more ring atoms;and    t=0 or more.    (i) When m is 0, then R'1 is H; (ii) When Rc is H or methyl, then one of Ra and Rb is other than methyl; (iii) When Ra+Rb+N form cyclic moiety having 3 or more ring atoms, then Rc and Rd are H, aliphatic group, aryl or heteroaryl; (iv) When Ra and Rb are H, aliphatic group, aryl or heteroaryl, then Rc+Rd+N form cyclic moiety having 3 or more ring atoms; (v) When Ra+Rb+N form cyclic moiety having 3 or more ring atoms, then Rc+Rd+N form cyclic moiety having 3 or more ring atoms; (vi) When Ra and Rc are H, aliphatic group, aryl or heteroaryl, then Rb+Rd+N form cyclic moiety having 5 or more ring atoms; and (vii) When Rb and Rd are H, aliphatic group, aryl or heteroaryl, then Ra+Rc+N form cyclic moiety having 5 or more ring atoms. INDEPENDENT CLAIMS are included for the following:    (1) preparation of 2,5-dimethylfuran, involves providing (5-methylfuran-2-yl)methanol and reducing (5-methylfuran-2-yl)methanol; and    (2) composition, which comprises furan-type compound (A), hydrogen and catalyst.
