Process for the alkoxylation of organic compounds in the presence of novel framework materials

A process for the alkoxylation of organic compounds, which comprises:

• reacting at least one organic compound, which is capable of being alkoxylated, with at least one alkoxylation agent in the presence of a catalyst system to form a polyether alcohol, wherein the catalyst system comprises a metallo-organic framework material comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to said metal ion,
• wherein the at least bidentate organic compound is selected from the group consisting of substituted or unsubstituted aromatic polycarboxylic acids, which may comprise one or more nuclei;
• and substituted or unsubstituted aromatic polycarboxylic acids, which comprise at least one heteroatom and which may have one or more nuclei.
