THE NOVEL SYNTHESES OF α-TRIFLUOROMETHYLATED KETONES FROM β-BROMOENOL PHOSPHATES
摘要:
A series of 1-aryl-3,3,3-trifluro-1-propanones have been synthesized from the reaction of FO2SCF2CO2Me with beta -bromoenol phosphates in the presence of Cul in moderate yield. The reaction mechanism was discussion, the electron-withdrawing substituent at the beta -position of the enol phosphates promoted the catalytic cleavage of the O-P bond in enol phosphates by fluoride ion.
