Sažetak
Multiple aminopropyl substitutions of the initial N, N', N''-trimethylguanidine leads to high intrinsic proton affinities and basicities culminating in APA = 268.4 kcal/mol in N, N', N''-tris(3-aminopropyl)guanidine. The reason behind a high proton affinity is identified as a strong cationic resonance in the central guanidine moiety and the strength of the intramolecular bonding, which is enhanced upon protonation.
