<p>Preparation of bicyclo[4.3.0]nonane-3(4),7(8)-dicarbonic acid comprises reacting bicyclo[4.3.0]nona-3,7-diene in a homogeneous organic phase with synthesis gas in the presence of organophosphorus compound in complex bond containing transition metal compound of the group VIII, in the presence of organophosphorus compound at 70-160[deg]C and 5-35 MPa; and oxidizing the obtained 3(4),7(8)-bisformyl-bicyclo-[4.3.0]nonane. Preparation of bicyclo[4.3.0]nonane-3(4),7(8)-dicarbonic acid by hydroformylation comprises reacting bicyclo[4.3.0]nona-3,7-diene in a homogeneous organic phase with synthesis gas in the presence of organophosphorus compound in complex bond containing transition metal compound of the group VIII, in the presence of a surplus of organophosphorus compound at 70-160[deg]C and 5-35 MPa; and either oxidizing the obtained 3(4),7(8)-bisformyl-bicyclo-[4.3.0]nonane or hydrogenating the obtained 3(4),7(8)-bisformyl-bicyclo-[4.3.0]nonane to give 3(4),7(8)-dihydroxymethyl-bicyclo[4.3.0]nonane, which reacts in an alkali melt at increased temperature and -pressure. An independent claim is included for a chemical compound such as bicyclo[4.3.0]nonane-3(4),7(8)-dicarbonic acid that is obtained by the process.</p> |
