✦ Synopsis

Natural abundance 13C and 15N NMR studies were carried out on a series of N -methylated and N -tert -butylated tetrazoles. Longrange 13C,1H and 15N,1H NMR coupling constants together with 1J (15N,13C) allowed unequivocal assignments of 13C and 15N chemical shifts for isomeric 1,5-and 2,5-disubstituted tetrazoles.

Reactions of diazonium salts with 4-substituted phenylaminopent-3-en-2-ones produce the corresponding 4-phenylimino-3-phenylhydrazonopentan-2-ones. On the other hand, the reaction of diazonium salt with 4-amino(or 4-methylamino)pent-3-en-2-one gives a mixture of two isomers approaching the tautomeri

Pyridofuroxan ([1,2,5]oxodiazolo [3,4-b]pyridine 1-oxide) undergoes isomerization between the N1oxide and N3-oxide forms which can be observed by the 1 H, 13 C and 15 N NMR spectroscopy but not by 14 N and 17 O NMR at ambient and low temperatures. The rearrangement becomes slower at low temperatures
