Synthesis of fluorine-containing methoxy-1,3-diketones
摘要:
A method is proposed for the synthesis of fluorine-containing methoxy-1,3-diketones by hydrolysis of N-phenylamino-alkenyl ketones, produced by the reaction of aniline and the respective methoxyalkynyl ketone in dioxane. With methanol an imine is also formed, and methyl trifluoroacetate is eliminated.
A method of synthesis of fluorinated alkoxyethynyl ketones is described, by acylation of terminal acetylenic compounds with fluoracyl chlorides in the presence of CuCl.
