SYNTHESIS OF ESTERS OF POLYFLUORO-SUBSTITUTED 2-METHYL-2,4-AIKADIENOIC AND 3-METHYL-2,4-AIKADIENOIC ACIDS BY HORNER-EMMONS OLEFINATION OF POLYFLUOROALKANALS
Vn. Odinokov et al., SYNTHESIS OF ESTERS OF POLYFLUORO-SUBSTITUTED 2-METHYL-2,4-AIKADIENOIC AND 3-METHYL-2,4-AIKADIENOIC ACIDS BY HORNER-EMMONS OLEFINATION OF POLYFLUOROALKANALS, Russian chemical bulletin, 44(11), 1995, pp. 2102-2104
Ethyl 2- and 3-methyl-6,6,7,7-tetrafluoro-2,4-heptadienoates and ethyl
2-methyl-6,6,7,7,8,8,9,9-octafluoro-2,4-nonadieno were synthesized by
condensing 2,2,3,3-tetrafluoropropanal or 2,2,3,3,4,4,5,5-octafluorop
entanal with ethyl 2-methyl-4-diisopropoxyphosphono- and ethyl 3-methy
l-4-diethoxyphosphono-2-butenoates under the conditions of the Homer-E
mmons reaction.
