Abstract:
In this work, 2–{5–[(2–phenylhydrazinylidene)methyl]
furan–2–yl}naphthalene-1,4-dione and 2–{4-[(2–
phenylhydrazinyliden)methyl]phenyl}naphthalene-1,4-dione
have been synthesized by reaction of 1-(furan-2-ylmethlidene)-
2-phenylhydrazine and 1-benzylidene-2-phenylhydrazine as
hydrazones with 1,4-naphthoquinone according to a well
documented procedure. Access to furylnaphthoquinones from
un activated quinones requires acid-inuced conditions, however
oxidation coupling reaction of activated quinones proceed under
neutral condition. The hydrazones were prepared from the
commercially aldehydes and phenyl hydrazine.
