The cyclization of phenacyl ethylene ketal (pek) hydrazones of glyoxals, benzaldehyde and acetaldehyde to pyrazoles is described; in the case of the hydrazones of benzaldehyde and acetaldehyde, the corresponding imidazoles are also formed.A mechanism is suggested for the formation of the imidazoles.
