Abstract
New bromodifluoromethyl enaminones 1a–1f and γ-bromo-β-morpholinopropenyl fluoromethyl ketones 2a, 2b were synthesized. N-Substituted bromodifluoromethyl enaminones 1a–1d do not react with triethyl or diethyl phosphites, whereas N-acylated enaminones 1e, 1f gave difluorodienyl phosphates 4a, 4b as Perkow rearrangement products. Fluoroketone 2a reacts easily with triethyl phosphite according to the Arbuzov protocol and a perspective building block – trifluoromethyl-containing phosphonate 7a is formed.
