    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing 3(4),8(9)-bisformyl-tricyclo[5.2.1.0 2.6 ]decane from dicyclopentadiene. SOLUTION: In the method for producing 3(4),8(9)-bis(aminomethyl)-tricyclo[5.2.1.0 2.6 ]decane by hydroformylating dicyclopentadiene and then aminating reducibly, is hydroformylation of dicyclopentadiene is performed by 2 steps. In a first hydroformylation step, 8(9)-formyl-tricyclo[5.2.1.0 2.6 ]decene-3 is obtained by using a group VIII transition metal compound containing a water soluble organic phosphorus (III) compound bonded as a complex state in a heterogeneous reaction system, and in a second hydroformylation step, thus obtained 8(9)-formyl-tricyclo[5.2.1.0 2.6 ]decene-3 is converted into 3(4), 8(9)-bisformyl-tricyclo[5.2.1.0 2.6 ]decane in the presence of a group VIII transition metal compound in a homogeneous organic phase.
