N2 - Vinyldiazene (CH2=CHN=NH) and 2-propenyldiazene, from the appropriate chlorocarbonyl compound and hydrazine under oxygen-free conditions, are characterized by (1) bimolecular disappearance, (2) expected n → Π* and Π → Π* transitions, (3) high volatility, and (4) nmr spectra.Vinyldiazene has the lowest bimolecular reaction rate constant of any monosubstituted diazene thus far examined, 0.0017 M-1 sec-1 in CH3CN at 25°.Cyclohexenyldiazene has been briefly studied.The position of the NH singlet in the nmr spectrum of alkenyldiazenes is unusually low, at τ — 5.95, and broadening with temperature is due to quadrupole broadening (14N-decoupling experiments).
