Abstract
1448228 3 - Substituted - 2,2 - dimethylcyclopropane - carboxylic acid esters NATIONAL RESEARCH DEVELOPMENT CORP 22 Oct 1974 [22 Oct 1973 13 June 1974] 49098/73 and 26316/74 Addition to 1413491 Heading C2C The invention comprises compounds having the general formula in the form of a substantially pure optical isomer with respect to the cyclopropane ring and having [R] configuration at the carbon atom of the cyclopropane ring carrying the COOR group and wherein (1) the compound is a crystalline isomer wherein R<SP>2</SP> and R<SP>3</SP> are each bromine and R is alpha-cyano-3-phenoxybenzyl, or (2) R<SP>2</SP> and R<SP>3</SP> are each fluorine and R is 3-phenoxybenzyl, alpha-cyano-3-phenoxybenzyl or 5-benzyl-3-furylmethyl, or (3) R<SP>2</SP> and are each chlorine and R is 3-phenoxybenyzl when the cyclopropane ring has [IR, cis or [IR, trans] configuration or R is 5-benzyl-3- furylmethyl when the cyclopropane ring has [IR, cis] configuration. Compounds of Formula I wherein R<SP>2</SP> and R<SP>3</SP> are each chlorine or each fluorine may be prepared by reacting a compound of the formula with a compound of the formula RQ where Q and Q<SP>1</SP> are groups which react together to form an ester linkage, the resolution into the desired configuration on the cyclopropane ring taking place before or after formation of the ester linkage. Compounds of Formula I wherein R<SP>2</SP> and R<SP>3</SP> are each bromine are prepared by dissolving (Œ)-alpha-cyano-3-phenoxybenzyl [IR, cis] 2,2 - dimethyl - 3 - (2,2 - dibromovinyl)- cyclopropane carboxylate in a solvent at elevated temperature and cooling the solution to precipitate the crystalline isomer. The compounds of the invention may be used as active ingredients in insecticidal compositions.
