<p>A process for the preparation of norbornene derivatives, characterized by reacting a norbornadiene derivative of general formula (2) [wherein R2, R3, R4, R5 and R6 are each independently a hydrogen atom or the like; l is an integer of 0 or 1; m is an integer of 0 or 1; and n is an integer of 0 or 1] with a halogen compound of general formula (3): [wherein Z is a phenylene group or the like; X is a chlorine atom or the like; and R7 is a hydrogen atom or the like] in the presence of a solvent such as N,N-dimethylformamide, a reducing agent, and a palladium catalyst wherein phosphine ligands of general formula (1) [wherein R1s are each independently a cyclic aliphatic hydrocarbon group] coordinate to a divalent palladium atom, and thereby obtaining a norbornene derivative of general formula (4) [wherein R8, R9, R10, R11, R12, l, m and n are as defined for R2, R3, R4,R5, R6, l, m, n in general formula (2); R13 is as defined for R7 in general formula (3); and Z is as defined for Z in general formula (3)], wherein the substituent Z in general formula (4) is configured in the exo form.</p> |
