Abstract: There are provided a compound capable of being a novel ligand allowing regioselective borylation to be performed in the aromatic borylation reaction, and a catalyst using the same compound. There is provided a bipyridyl compound represented by a general formula (1): (wherein A represents a single bond, a vinylene group or an ethynylene group;X represents an oxygen atom or a sulfur atom;n pieces of R1 may be the same or different, and R1 represents a hydrogen atom, a halogen atom, an optionally substituted hydrocarbon group, an optionally substituted alkoxy group, an optionally substituted aryloxy group, an optionally substituted amino group, a cyano group, a nitro group, or an alkoxycarbonyl group, or two adjacent R1 may form a saturated or unsaturated ring structure optionally containing a hetero atom together with the carbon atoms bonded to the two R1;R2 represents a hydrogen atom, an optionally substituted hydrocarbon group, an optionally substituted alkoxy group, or an optionally substituted aryloxy group; andn represents a number of 1 to 4).
