Aminoketones were trifluoromethylated by using trialkyl(trifluoromethyl)silanes without any reaction promoters. Formation of cyclic intermediates is proposed to be possible transition states in this reaction. Moderate diastereoselectivities were observed in the trifluoromethylation of the aminoketones having a side chain.

We are studying the synthesis of organic reagents under the conditions of the phase-transfer catalysis (PTC) aimed for implementation in the production industry [4–6]. A part of these studies are attempts to use the PTC achievements in organic synthesis by an example of oxo group hydrogenation with NaBH4 insufficiently examined in such environment [7, 8]. Ketone 1 and NaBH4 are sufficiently different
