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.
合成了新的溴二氟甲基烯酮1a-1f和γ-溴-β-吗啡基丙烯基氟甲基酮2a、2b。N-取代的溴二氟甲基烯酮1a-1d不与三乙基或二乙基膦酸酯反应,而N-酰基化的烯酮1e、1f则形成了二氟二烯基磷酸酯4a、4b作为Perkow重排产物。氟酮2a根据Arbuzov协议容易与三乙基膦酸酯反应,形成了一个前景建筑模块-三氟甲基含磷酸酯7a。
