There are disclosed a process for producing a coupling compound of formula (1): <?in-line-formulae description="In-line Formulae" end="lead"?>(Y-)<SUB>(n-1)</SUB>R<SUP>1</SUP>-R<SUP>2</SUP>-(R<SUP>1</SUP>)<SUB>(n'-1)</SUB>, (1)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>1 </SUP>and R<SUP>2 </SUP>independently represent a substituted or unsubstituted aryl group, which process is characterized by reacting an unsaturated organic compound of formula (2): <?in-line-formulae description="In-line Formulae" end="lead"?>n'(R<SUP>1</SUP>X<SUP>1</SUP><SUB>n</SUB>) (2)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein n, n', and R<SUP>1 </SUP>are the same as defined above, and X<SUP>1 </SUP>is the same or different and independently represents a leaving group and bonded with a sp2 carbon atom of R<SUP>1 </SUP>group, with a boron compound of formula (3): <?in-line-formulae description="In-line Formulae" end="lead"?>m{R<SUP>2</SUP>(BX<SUP>2</SUP><SUB>2</SUB>)<SUB>n'</SUB>} (3)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>2 </SUP>and n' are the same as defined above, X<SUP>2 </SUP>represents a hydroxy group, an alkoxy group, in the presence of a catalyst containing (A) a nickel compound, and (B) a nitrogen-containing cyclic compound, and the catalyst.
