A conformational study of 1,4-diacetyl-1,4-dihydro-6,7-dimethylquinoxaline is carried out by low temperature nmr in CD2Cl2. Important acetyl rotation induced shifts have been observed for the peri and ortho protons. These results, together with low t

The electrochemical reduction of 1,3-diketones C6H5—CO—CR1R2—CO—R3 (R1 = H, CH3; R2 = CH3, CH2C6H5; R3 = CH3, C6H5) in an hydroorganic medium corresponds to a bielectronic process and leads to 1,2-cyclopropanediols which, in most cases, are o

It is shown by X-ray crystallography that 2-nitrosoquinoxaline crystallizes as a dimer, the structure of which is established. In solution the monomeric form predominates and the dimerisation equilibrium constant is measured. The electrochemical redu

The reaction of o-phenylenediamine with a β-ketoacid, leads in most cases to quinoxalinones. Their structure has been determined as well as that of their corresponding hydrazones. The reaction of hydrazine with these quinoxalinones gives dihydropyri

The reaction of 2,3-diaminopyridine with the dimeric 4,5-dimethylcyclohexa-3,5-dien-1,2-dione gives 7,8-dimethylpyrido[2,3-b]quinoxaline, 1, in good yields; in the same way 3,4-diaminopyridine gives the 7,8-dimethylpyrido[3,4-b]quinoxaline 2. The ele
