Iridium-Catalyzed Coupling of Simple Primary or Secondary Amines, Aldehydes
Trimethylsilylacetylene: Preparation of Propargylic Amines. — The multi49- 149 and
component coupling reaction of aldehydes (II), acetylene (III) with primary or secondary amines is found to be promoted by an Ir catalyst. Whereas the coupling of secondary
amines (I) cleanly gives products (IV), the outcome of the reaction with primary amines
(V) or (VIII) depends on the reaction conditions and the stoichiometry of the reactants.
