Conclusions
- 1.
Pentacyanocobaltate and cyanodipyridylcobaltate catalyze the addition of hydrogen in the 1,4 position of the diene system and to the 5,6 bond of the dienone. In their presence the dienol is hydrogenated both at the 5,6 bond and at the 3,4 bond, which is conjugated with the OH group.
- 2.
Cyanodipyridylcobaltate does not catalyze the hydrogenation of heptenones, where the strict selectivity of its action in the step of adding the first mole of hydrogen to 6-methyl-3,5-heptadien-2-one is determined.
