Abstract
Abstract Perhaloalkylvinylcyclopropanecarboxylates having the general formula: ##STR1## wherein one of Y and Z is a perhaloalkyl group and the other is hydrogen, halogen, or lower alkyl; and R is --OR 1 where R 1 is an optionally substituted biphenylmethyl radical are disclosed. The insecticidal efficacy and preparation of the compounds and their intermediates are described and exemplified.

Claim 1
Independent Claim
89 words
A compound of the formula ##STR11## wherein one of Y and Z is a perhaloalkyl group having 1 to 4 carbon atoms and the other is hydrogen, halogen, or lower alkyl; and R is --OR 1 where R 1 is a group of the formula ##STR12## in which R 2 is hydrogen, R 3 is vinylene; R 4 and R 5 are independently hydrogen, lower alkyl, halogen, or haloalkyl; and R 6 is phenyl which may be substituted with one to three substituents selected from halogen and lower alkyl.
Claim 2
Dependent Claim
89 words
A compound of the formula ##STR11## wherein one of Y and Z is a perhaloalkyl group having 1 to 4 carbon atoms and the other is hydrogen, halogen, or lower alkyl; and R is --OR 1 where R 1 is a group of the formula ##STR12## in which R 2 is hydrogen, R 3 is vinylene; R 4 and R 5 are independently hydrogen, lower alkyl, halogen, or haloalkyl; and R 6 is phenyl which may be substituted with one to three substituents selected from halogen and lower alkyl.
