Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
50 words
A dihalovinyl-spiroalkanecyclopropane derivative of the formula ##EQU2## wherein R 1 and R 2 independently each represents a halogen atom; R 3 represents a hydrogen atom, or alkynyl of 2 to 4 carbon atoms; R 4 represents phenyl substituted by phenoxy and n is an integer of from 2 to 5.
Claim 2
Dependent Claim
50 words
A dihalovinyl-spiroalkanecyclopropane derivative of the formula ##EQU2## wherein R 1 and R 2 independently each represents a halogen atom; R 3 represents a hydrogen atom, or alkynyl of 2 to 4 carbon atoms; R 4 represents phenyl substituted by phenoxy and n is an integer of from 2 to 5.
Claim 3
Dependent Claim
37 words
A dihalovinyl-spiroalkanecyclopropane derivative as claimed in claim 1, wherein R 1 and R 2 each represents a halogen atom; R 3 represents a hydrogen atom or ethynyl and n is an integer of from 2 to 3.
Claim 4
Dependent Claim
19 words
A dihalovinyl-spiroalkanecyclopropane derivative as claimed in claim 2 wherein R 1 and R 2 each represents a chlorine atom.
Claim 5
Dependent Claim
29 words
A dihalovinyl-spiroalkanecyclopropane derivative as claimed in claim 2 wherein R 1 and R 2 each represents a chlorine atom; R 3 represents a hydrogen atom and n is 3.

Claim 7
Independent Claim
72 words
A method of combating insect or arachnid pests at a locus which comprises applying to the locus a pesticidally active amount of a dihalovinyl-spiroalkanecyclopropane derivative of the formula ##EQU3## wherein R 1 and R 2 independently each represents a halogen atom; R 3 represents a hydrogen atom or alkynyl of 2 to 4 carbon atoms; R 4 represents phenyl substituted by phenoxy and n is an integer of from 2 to 5.
Claim 8
Independent Claim
72 words
A method of combating insect or arachnid pests at a locus which comprises applying to the locus a pesticidally active amount of a dihalovinyl-spiroalkanecyclopropane derivative of the formula ##EQU3## wherein R 1 and R 2 independently each represents a halogen atom; R 3 represents a hydrogen atom or alkynyl of 2 to 4 carbon atoms; R 4 represents phenyl substituted by phenoxy and n is an integer of from 2 to 5.
Claim 9
Dependent Claim
35 words
