Three series of 3,7-bis(arylazo)-2,6-dimethyl-1H-imidazo[1,2-b]pyrazoles were prepared starting from N-aryl-2-oxopropanehydrazonoyl chlorides. The acid dissociation constants pKa were determined and correlated with the Hammett equation. The results of suc

tert-Butyl isocyanide (2) reacts with acceptor-substituted nitrile imines to give derivatives of tetrahydro-1,2,5,6-tetrazocines 3 along with substituted 5-hydrazonoyl-1,2,4-triazoles 4. Replacement of 2 with aryl or sec-alkyl isocyanides leads to substituted α-hydrazonoamides (6B) rather than to analogues of 3; removal of the acceptor group in 1 is likewise detrimental. - The structure of 3 has been established by means of an X-ray diffraction analysis of 3d.
