Reaktionsschritte

A special house made pressure reactor, a 50 ml 10 bar glass reactor with steel mantle and a magnetic stirring bar, was charged with catalyst, 4-hydroxyacetyl-catechol (produced according to Example 2) and t-butyl methyl ether. The reactor was evacuated and filled with hydrogen. Hydrogenation was started by stirring at 5 bar hydrogen pressure while heating to 40° C. By the end of the reaction the hydrogen was replaced by air, the slurry was filtered, the catalyst was washed with ethyl acetate. After evaporation of the solvents and drying at 1 mbar the product was analyzed quantitatively. The details of some reactions and the results are shown in Table 1.
