5-(N,N-Dialkylamino)-2-furfurylidene-N,N-dialkylimminium salts I (the vinamidinium salts of furan) react with arenediazonium salts to give products of ipso substitution in position 2 of the furan ring, i.e. 5-(N,N-dialkylamino)-2-azoarenefuran salts II.The structure of these products was evidenced by 1H NMR and UV spectral data.
