Abstract: Provided are compounds represented by, for example, formula (1) (wherein R1, R2, R3 and R4 each independently represent a hydrogen atom, an alkyl group, or a heteroaryl group, not all of R1, R2, R3 and R4 being hydrogen atoms), a luminescent material including at least one compound selected from among the compounds, and a luminescent element including the luminescent material.

Abstract: A compound represented by formula (I). In formula (I), each L independently represents a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, n indicates the number of L groups, and is either 1 or 2, each Q independently represents a substituted or unsubstituted 3,6-di-t-butyl-9H-carbazol-9-yl group, a substituted or unsubstituted 3,6-diphenyl-9H-carbazol-9-yl group, or a substituted or unsubstituted 3-phenyl-6-t-butyl-9H-carbazol-9-yl group, and in indicates the number of Q groups, and has a value of 5?n.

Abstract: A compound represented by a formula (II), an N-oxide compound, or a salt thereof: wherein R1 is a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, or a halogeno group; R2 is a substituted or unsubstituted 5- to 6-membered heteroaryl group; R3 is a substituted or unsubstituted C6-10 aryl group or a substituted or unsubstituted 5- to 10-membered heteroaryl group; Y is an oxygen atom, a nitrogen atom, or a sulfur atom; A1, A2, A3 and A4 are each independently a carbon atom or a nitrogen atom, provided that two or more of A1 to A4 do not represent nitrogen atoms at the same time; X is a substituent; n represents the number of chemically acceptable substituents represented by X, and is any one of integers of 0 to 5; and when n is 2 or more, the substituents X may be the same or different from each other.

Abstract: Provided is a method for producing a tetrafluoro nitrogen-containing heterocyclic compound such as tetrafluoropyrrolidine in good yield and at low cost. The method comprises the steps of: (A) reacting a compound represented by the formula (I) with fluorine gas to produce a tetrafluoro compound represented by the formula (II), (B) converting the tetrafluoro derivative represented by the formula (II) to a compound represented by the formula (III), and (C) reacting the compound represented by the formula (III) with an amine compound represented by the formula NH2R9 to produce a tetrafluoro nitrogen-containing heterocyclic compound represented by the formula (IV) or salt thereof.

Abstract: Novel amidine compounds which may be active ingredients in herbicides that are reliably effective at a lesser dose and highly safe, and herbicides containing these compounds as active ingredients are provided. Amidine compounds represented by a formula (1?) and herbicides containing at least one kind of these compounds as active ingredients, [wherein G is an optionally substituted nitrogen-containing heterocyclic group represented by a formula (2?) with a proviso that the number of carbons constituting the nitrogen-containing heterocycle of the nitrogen-containing heterocyclic group is 10 or less and that 2H-Indazole ring is excluded; Q? represents cyano or the like; and A? represents substituted phenyl or the like].
