3-Bromo-3,3-difluoropropene Chemical Properties,Usage,Production
Uses
3-Bromo-3,3-difluoropropene, when mixed with lithium bromide, provides a convenient route to prepare gem-(difluoroallyl) lithium, a reagent of general use in the formation of gem-difluorinated organic compounds. Umpolung asymmetric difluoroallylation of hydrazones with 3-bromo-3,3-difluoropropene (BDFP) under palladium catalysis. In addition, aldehydes and ketones reacted with 3-bromo-3,3-difluoropropene in the presence of the acid-washed zinc powder at 0°C to room temperature to afford gem-difluorohomoallyl alcohols in moderate yields[1-3].
