Versuchsvorschrift

56.5 g of crotonic acid diethylamide 36.9 g of ethanol, 1.27 g of pyridine and 2.74 g of Co2 (CO)8 are reacted analogously to Example 1 for 1.5 hours at 170° C. under a carbon monoxide pressure of 150 bar (+approx. 2% by volume of hydrogen). Analysis showed that 99.6 mol % of the crotonic acid diethylamide had reacted. Relative to this, C5 -dicarboxylic acid derivatives containing mixed derivative groups had been formed at a selectivity of conversion of 97.4 mol %; 2-methylsuccinic acid 1-ethylester-4-diethylamide was 93.6% of this. In addition, butyric acid diethylamide and but-3-enoic acid diethylamide had been formed at selectivities of conversion of 1.2 mol % and 0.4 mol %, respectively.
