Anthranilamide compounds, process for their production and pesticides containing them

An anthranilamide compound represented by formula (Ia) or its salt:

• wherein R1a is halogen or alkyl, R1c is F, Cl or alkyl, R1b and R1d are hydrogen, R2 is CF3 or halogen, R3a is halogen or CF3, R3b, R3c and R3d are hydrogen;
• A is alkyl substituted by Y;
• Y is C3-4 cycloalkyl which may be substituted by at least one group selected from halogen and alkyl;
• and n is 0 or 1.

A process for producing an anthranilamide compound of formula (I) or its salt:

• wherein m is 1 or 2 and R1 is halogen or alkyl;
• R2 is halogen or CF3;
• q is 1 and R3 is substituted at the 3-position and is halogen or CF3;
• A is alkyl substituted by Y;
• Y is C3-4 cycloalkyl which may be substituted by at least one group selected from halogen and alkyl;
• and n is 0 or 1;
• provided that when R1 is a fluorine atom, a chlorine atom, a bromine atom or methyl substituted at the 2-position of the benzene ring and another R1 is halogen substituted at the 4-position of the benzene ring, the halogen at the 4-position is a fluorine atom or a chlorine atom;
• wherein the method comprises (1) reacting a compound of formula (II):
• wherein R1, A and m are as defined above, with a compound represented by formula (III):
• wherein R2, R3, n and q are as defined above and Z is a chlorine atom, OH or C1-4 alkoxy, or
• (2) reacting a compound represented by formula (IV):
• wherein R1, R2, R3, m, n and q are as defined above with a compound represented by the formula (V):
• A-NH2, wherein A is as defined above.
