Cross-linked cyclic amine compounds and agents for pest control

Cyclic amine compounds represented by formula (1)

• or salts thereof or N-oxides thereof,
• wherein Cy1 represents an unsubstituted or substituted aromatic ring;
• X represents oxygen, sulfur, unsubstituted or substituted nitrogen, sulfinyl, or sulfonyl;
• R1a and R2a, R1a and R4a, R2a and R3a, or R3a and R4a form saturated rings together;
• R1a, R1b, R2a, R2b, R3a, R3b, R4a, R4b, and R5 which do not form the saturated rings are each independently hydrogen, hydroxyl, halogen, unsubstituted or substituted amino, nitro, or an organic group;
• Cy2 represents an unsubstituted or substituted aromatic ring with a proviso that Cy2 is an unsubstituted or substituted heteroaromatic ring when R1a and R2a faun a saturated ring together and Cy1 is an unsubstituted or substituted phenyl, and Cy2 is a substituted pyridin-2-yl having one, or more cyano as a substituent when Cy1 is an unsubstituted or substituted phenyl and Cy2 is a pyridin-2-yl,
• wherein the cyclic amine compounds represented by formula (1) are cyclic amine compounds represented by formula (2)
• wherein Q, Q1, Q2, Q3, Q4, and Q5 are C or N, Q1, Q2, Q3, Q4, and Q5 may be substituted, ring including Q may be substituted, and n is 1 or 2.

Agents for pest control comprising at least one of cyclic amine compounds represented by formula (3),

• salts thereof, or N-oxides thereof as an active ingredient,
• wherein Cy11 represents an unsubstituted or substituted aromatic ring;
• X11 represents oxygen, sulfur, unsubstituted or substituted nitrogen, sulfinyl, or sulfonyl;
• R11a and R21a, R11a and R41a, R21a and R31a, or R31a and R41a form saturated rings together;
• R11a, R11b, R21a, R21b, R31a, R31b, R41b, and R51 which do not form the saturated rings each independently represents hydrogen, hydroxyl, halogen, unsubstituted or substituted amino, nitro, or an organic group;
• and Cy21 represents an unsubstituted or substituted aromatic ring,
• wherein the cyclic amine compounds represented by formula (3) are cyclic amine compounds represented by formula (2)
• wherein Q, Q1, Q2, Q3, Q4, and Q5 are C or N, Q1, Q2, Q3, Q4, and Q5 may be substituted, ring including Q may be substituted, and n is 1 or 2.
