Watanabe, Shoji,Fujita, Tsutomu,Sakamoto, Masami,Hamano, Hiroyuki,Kitazume, Tomoya,Yamazaki, Takashi

, p. 15 - 19 (2007/10/03)

α-Trifluoromethyl amines (IV) were prepared in three steps: preparation of α-trifluoromethyl ketones (I), their conversion to benzyloximes (II), and reduction of the oximes (II) with lithium aluminium hydride and sodium methoxide. For example, α-trifluoromethyltridecylamine was obtained from the reduction of trifluoromethyl dodecyl ketone benzyl oxime. Elsevier Science S.A.
