By quantitative cyanoethylation of polyamines combined with catalytic hydrogenation (Raney nickel) of the resulting polynitriles, poly(trimethylene imine) cascade molecules are accessible in high yields and high purities. Starting from ammonia, five generations of highly symmetrical dendrimers without structural defects were prepared with this reaction sequence.
