Abstract
The novel chemical compound, 3(4),7(8)-dihydroxymethylbicyclo[4.3.0]nonane and a process for its preparation, wherein bicyclo[4.3.0]nona-3,7-diene is reacted with synthesis gas in homogeneous organic phase in the presence of transition metal compounds of Group VIII of the Periodic Table containing complex-bound organophosphorus compound, at 70 to 160° C. and pressures of 5 to 35 MPa, and the 3(4),7(8)-bisformylbicyclo[4.3.0]nonane thus obtained is hydrogenated.
