    Abstract: A new “one-flask” synthesis of 3,5-disubstituted 1,2,4-triazoles has
    successfully been developed to synthesize a series of 3,5-disubstituted 1,2,4-triazoles.
    The transformation involves the 1,3-dipolar cycloaddition reaction of hydrazonoyl
    hydrochlorides with oxime intermediates prepared from aldehydes with
    hydroxylamine hydrochloride in the presence of excess amount of triethylamine. In
    this “one-flask” 1,3-dipolar reaction, hydrazonoyl hydrochlorides was concerned as
    the masked 1,3-dipole nitrilimine under basic condition. Furthermore, this newly
    developed methodology can be applied to various aldehyde substrates including
    aliphatic, cyclic aliphatic, aromatic, and heterocyclic aldehydes.
