## Abstract

1R,cis-trifluoromethylethenylcyclopropanecarbonyl compounds of the formula ##STR1## in which X is halogen and R is halogen, hydroxy, lower alkoxy or an optionally substituted 1,1'-biphenyl-3-methyloxy group, their method of preparation and utility as insecticides and intermediates therefore are described and exemplified.

## Claims

### Claim 1

A 1R,cis-trifluoromethylethenylcyclopropanecarbonyl compound of the formula ##STR5## in which X is halogen, R is an alcohol residue of the formula ##STR6## in which R.sup.1 and R.sup.2 are independently hydrogen, lower alkyl or halogen.

### Claim 2 (depends on 1)

The compound of claim 1 in which R is the alcohol residue of formula II.

### Claim 3

The compound (2-methyl-[1,1'-biphenyl]-3-yl)methyl 1R,cis-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecar boxylate.
