Summary Of The Invention
Novel benzophenonehydrazone derivatives represented by the formula (I):
wherein, R1 is halogen; R2 is hydrogen or C1-4 alkyl; R3 is cyano, optically substituted C1-4 alkyl, C2-4 alkenyl, C3-4 alkynyl, C1-4 alkyl-carbonyl or C1-4 alkoxy-thiocarbonyl; R4 is hydrogen, phenyl, optionally substituted C1-6 alkyl, optionally substituted C2-8 alkenyl, -CO-R8, -CO-O-R9 or
R5 is hydrogen, formyl, phenyl, optionally substituted C1-8 alkyl, optionally substituted C2-8 alkenyl, optionally substituted C3-8 alkynyl, optionally substituted C1-8 alkyl-carbonyl, optionally substituted C1-6 alkyl-oxalyl, optionally substituted C1-8 alkoxy-carbonyl, optionally substituted C1-8 alkoxy-oxalyl, optionally substituted C3-8 cycloalkyl-carbonyl, optionally substituted C2-8 alkenyl-carbonyl or optionally substituted benzoyl; R6 is hydrogen or halogen; R7 is hydrogen, halogen or C1-2 alkyl, C1-4 alkyl-carbonyl or C1-4 alkoxy-thiocarbonyl; n is 0, 1 or 2, provided that n is 0 when R3 is cyano, C1-4 alkyl-carbonyl or C1-4 alkoxy-thiocarbonyl, is a single bond of Anti form or of Syn form.
The benzophenonehydrazone derivatives of the formula (I) have excellent insecticidal activities.
