ABSTRACT:
A method for the preparation of enamines wherein a conjugated diene is reacted with a secondary amine, carbon monoxide and hydrogen (synthesis gas) in solvent solution in the presence of a rhodium catalyst. In accordance with the preferred embodiment, butadiene is reacted with a dialkylamine and synthesis gas in an organic solvent in the presence of a rhodium catalyst to provide the corresponding 1,3-pentadienyl dialkylamine in good yield and with good selectivity. This may be illustrated, for example, by the following equation: ##STR1##
