    Abstract: The present invention relates to a method for preparing 2'-O-fucosyllactose, the 2'-O-fucosyllactose obtainable by this method and the use thereof. The method comprises reacting the persilylated, protected fucose derivatives of the formula (I) below, with at least one tri(C1-C6-alkyl)silyl iodide and subsequently reacting the product thus obtained with the compound of the general formula (II), in the presence of a base. In the formulae (I) and (II), the variables are each defined as follows: RSi are the same or different and are a residue of the formula SiRaRbRc; R1 is a C(=O)-R11 residue or an SiR12R13R14 residue, R2 are the same or different and are C1-C8-alkyl or together form a linear C3-C6- alkanediyl, which is unsubstituted or has 1 to 6 methyl groups as substituents; R3 are the same or different and are C1-C8-alkyl or together form a linear C1-C4- alkanediyl, which is unsubstituted or has 1 to 6 methyl groups as substituents.

    2 -CH
    2 -OH (I) or at least one branched alcohol of general formula (II) R
    1 -CH
    2 -CHR
    1 -CH
    2 -OH (II), at least one oil-soluble complex compound of at least one metal of the 8th, 9th, or 10th group of the periodic table of the elements, which is selected from complex compounds that have at least one ligand L
    1 that is at least bidentate, at least one coordination site of L
    1 being a nitrogen atom, and at least one acid of general formula (III) R
    1 -CH
    2 -COOH (III) in the form of a salt of said acid, the groups R
    1 being selected from C
    2 -C
