Pd(OAc)2-catalyzed oxidative carbonylation of aromatics: Synthesis of naphthalenecarboxylic acids

The liquid-phase oxidative carbonylation of aromatics leading to aromatic carboxylic acids is studied to develop new approaches to 2,6- naphthalenedicarboxylic acid (NDA) preparation. It is shown that the catalytic system Pd(OAc)2/K2S2O8 allows the synthesis of naphthalic anhydride (NAn) by direct oxidative carbonylation of naphthalene under mild conditions (25 C, 2 atm CO). The subsequent alkaline hydrolysis of NAn and isomerization of the obtained 1,8-naphthalenedicarboxylic acid salt is known to lead to NDA.

Antitumor dibenzofluorene derivatives

Dibenzofluorene derivatives having a formula selected from the group consisting of and salts thereof have antitumor activity. At least one of R1-R13in formula (I) or R1-R12in formula (II) is —R14Z. R14is a substituted or unsubstituted amino or amido group having from 1-12 carbon atoms, and Z is a substituted or unsubstituted heterocyclic group having from 1-12 carbon atoms. The remainder of R1-R13in formula (I) or R1-R12in formula (II) are independently selected from the group consisting of hydrogen, hydroxyl, halogen, nitro, substituted or unsubstituted amino or amido groups having from 1-12 carbon atoms, and alkyl groups having 1-12 carbon atoms.
