Polyamines, structurally related to putrescines and spermidines, are easily obtainable via hydroaminomethylation of methylallylphthalimide with primary or secondary amines. In addition, hydroaminomethylation of monoolefins with urea as a synthetic equivalent for ammonia, in contrast to other methods (e.g. the alkylation of ammonia or ammonium salts), allows selective synthesis of symmetric tertiary
Verfahren zur Hydroaminomethylierung von Verbindungen, welche mindestens eine Doppelbindung enthalten, wobei eine Verbindung, welche mindestens eine Doppelbindung enthält, mit Ammoniak oder einer Ammoniakquelle unter Zuführung von H2 und CO in Gegenwart eines katalytischen Systems aus einem Ruthenium-Komplex und eines organischen PhosphorLiganden umgesetzt wird.
The direct synthesis of tertiary amines from ammonia and olefins is presented. Using a combination of Ru3(CO)12 and 2‐phosphino‐substituted imidazole ligand as catalyst system allows for hydroaminomethylation reactions of bulk aliphatic and functionalized olefins. Tertiary amines are obtained in an atom‐efficient domino process in moderate to good isolated yields (45–76 %) with excellent regioselectivities
