Notes:
The reaction of bis(vinamidinium salts) (5a, 6) and amidinium-vinamidinium salts (7, 21) with primary amines was studied. Whereas the condensation of 6 and 7a with p-phenylenediamine and 4,4′ diaminostilbene gave rise to polymeric vinamidines (12, 18), 5a and 7b reacted with aromatic amines and diamines to give pyrrole and imidazole derivatives. The reaction of p-aminophenylacetic acid with DMF-POCl3 produced a new amidinium-vinamidinium salt (21) which could be converted into a donor-acceptor substituted diazaterphenyl derivative (22) displaying a strong solvatochromism. - The crystal structure analysis of the 2,2′-bis(vinamidinium salt) 5b revealed a 73° twist angle between the planes of the vinamidinium moieties.
