New 3-hydroxy-1,5-benzodiazepin-2-ones were synthesized through condensation between ophenylenediamines with glycidic ester. Alkylation and oxidation of some of the obtained compounds were also explored in different conditions yielding various oxidized and alkylated benzodiazepines. The structural elucidation of the synthesized compounds was achieved by MS, NMR spectroscopy and also through X-ray diffraction analysis. The glycidic ester was thus shown to be an interesting synthon in the synthesis of new 1,5-benzodiazepines used in alkylation and oxidation reactions.

The title compound, dicarbonyl-1kappa(2)C-di-mu-chloro-1:2kappa(4)Cl-[cis,cis-2(eta(4))-1,5-cyclooctadiene]dirhodium(I), [Rh(2)Cl(2)(C(8)H(12))(CO)(2)], consists of a dichloro-bridged dimer of rhodium, with a non-bonded Rh.Rh distance of 3.284 (2) A. One Rh atom is coordinated to two carbonyl ligands, while the other Rh atom is coordinated to the cyclooctadiene moiety.
