Abstract: Iminoacetonitrile (1) has been prepared by two methods:(i) thermal decomposition of the tosylhydrazone salts 13 at 200" C and (ii) Ar matrix photolysis of azidoacetonitrile (15). Ab initio calculations indicate that 1Z is of slightly lower energy than lE, and this is confirmed by the IR spectra with use of the thermal methods. lE/lZ undergo photochemical interconversion, giving a ca. 3: l photostationary E: Z ratio. IE and 1Z are fully ...
