It was shown by means of the UV spectra that a sydnoneimine base is formed from 3-cyclohexyl sydnoneimine hydrochloride by the action of an equivalent amount of sodium hydroxide in solutions of absolute alcohols.The sydnoneimine base is also formed in the case of solvolysis of N6-trimethylsilyl-3-cyclohexylsydnoneimine in methanol.The sydnoneimine base in solutions exists in equilibrium with the chain isomer, viz., the nitrile.The fraction of the cyclic isomer increases as the electron-donor properties of the substituent in the 3 position become more pronounced.
