反応手順

1.2 g (8.0 mmol) 4-Nitro-o-xylene and 0.66 g (22 mmol) paraformaldehyde were added to a mixture of 1.2 g catalyst in 4 ml of dimethylsulphoxide. The catalyst had been prepared by heating for 24 hours at 500° C. a composition containing 20 g K2CO3 per 100 g gamma-alumina, i.e. 2.89 mmol K+ /g Al2O3. The reaction mixture was stirred under nitrogen at 20°-25° C. The conversion of 4-nitro-o-xylene and the selectivity during the reaction were determined by gas-liquid chromatography, whereby the alcohols were analysed via their trimethylsilyl ethers. The results are given in Table I.
