Derivatives of Halogenated Aldehydes. XVII. Reactions of N-(1,2,2,2-Tetrachloroethyl)trichloroacetaldimine with Alcohols and ThioalcoholsReactions of N-(1,2,2,2-tetrachloroethyl)trichloroacetaldimine 1 with methanol lead to 1,2,2,2-tetrachloroethyl-(2,2,2-trichloro-1-methoxyethyl)amine 2a, N-(2,2,2-trichloro-1-methoxyethyl)trichloroacetaldimine 3a and bis-(2,2,2-trichloro-1-methoxyethyl)amine 5. After the reaction of the aldimine 1 with ethanol or propanol only the N-(1-alkoxy-2,2,2,-trichloroethyl)trichloroacetaldimines 3b, c are isolated; with thioalcohols only the N-(1-alkylthio-2,2,2-trichloroethyl)-trichloroacetaldimines 4a-c are obtained. The aldimines 3a-c and 4b, c are decomposed on treatment with hydrochloric acid and an excess of an alcohol or thioalcohol to yield the amine hydrochlorides 6a-c, 7b, c, which are transformed into the amines 8a-c and 9b, c. From these amines the derivatives 10-15 are prepared.
