The preparative procedure for the synthesis of N-(2,2,2-trichloro-1-hydroxyethyl)aldimines from the corresponding aldehyde, chloral, and ammonium acetate was developed. Preparative silylation and acylation of their hydroxy groups were acomplished for the first time. The possibility to use the synthesized O-trimethylsilyl and O-acetyl derivatives as the synthetic equivalents of N-nonsubstituted imines in the reactions with cyclopropenone was investigated.
