    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; and n represents a number of 1 to 4).

    Abstract: Provided are a donor-acceptor type compound having a novel structure and its use.
    An enamine compound represented by general formula (1)




    (in the formula:

    R1 represents an electron-withdrawing group;
    A represents a divalent aromatic hydrocarbon group which may contain a substituent, a divalent aromatic heterocyclic group which may contain a substituent or a divalent unsaturated aliphatic hydrocarbon group which may contain a substituent;
    R2 represents a hydrogen atom or a hydrocarbon group which may contain a substituent;
    R3 and R4 are the same or different from each other and represent an aromatic hydrocarbon group which may contain a substituent or an aromatic heterocyclic group which may contain a substituent, or R3 and R4 together form an optionally substituted bicyclic aromatic heterocyclic group containing two or more nitrogen atoms or a nitrogen atom and an oxygen atom or a sulfur atom, or a tricyclic aromatic heterocyclic group which may contain a substituent; and
    R2 and A, or R2 and R3 may together form a cyclic structure).
