| titleOfInvention | 3-substituted cyclopropane carboxylic acids and derivatives thereof |
| abstract | 1446304 3 - Substituted cyclopropane carboxylic acid derivatives NATIONAL RESEARCH DEVELOPMENT CORP 15 Aug 1973 [25 May 1972 30 June 1972 21 Dec 1972 24 May 1973] 22010/75 22011/75 22012/75 and 22013/75 Divided out of 1413491 Heading C2C The invention comprises compounds having the general formula wherein R<SP>1</SP> is hydrogen or methyl; R<SP>2</SP> is hydrogen, halogen or alkyl; R<SP>3</SP> is hydrogen, halogen, alkyl or carboalkoxy; at least one of R<SP>2</SP> and R<SP>3</SP> representing a halogeno group and E is halogen or OE<SP>1</SP> where E<SP>1</SP> is hydrogen, a cation or alkyl; with the proviso that when R<SP>1</SP> is hydrogen and the compound is racemic, R<SP>2</SP> and R<SP>3</SP> are not both chlorine. They may be prepared by reacting a phosphorane of formula with a carbonyl compound of the formula wherein Z<SP>4</SP> is an organic residue which forms a stable triorgano phosphorus oxide and E<SP>2</SP> is alkyl, and if desired, converting the resulting alkyl ester into the corresponding free acid or acid halide. The phcsphorane of Formula X may be prepared by reacting a substituted methylhalide of the formula R<SP>3</SP>(R<SP>2</SP>)CH-halogen with a triorgano phosphine of formula P(Z<SP>4</SP>) 3 and if necessary treating the resulting quaternary phosphonium halide with a base to bring about dehydrohalogenation. |
