Two functionalizations of the unsaturated fatty alcohol oleylalcohol with carbon monoxide via the homogeneous catalyzed reactions hydroaminomethylation and hydroesterification are shown. In this way it is possible to gain new biosurfactants and biopolymers. The tandem reaction hydroaminomethylation was optimized to high yields for adducts with diethylamine. Hydroesterification of oleylalcohol showed high yields for the hydroxyl esters. An approach for separation of catalyst and products by employing a thermomorphic solvent system is presented.
