The perfluorinated tertiary amines (SF₅)₂NCF₃ [1], (SF₅)₂NC₂F₅, and (SF₅)₂NC₃F₇ have been prepared by the following scheme. Their overall yields were found to decrease markedly with respect to increases in the length of the perfluoro- {A figure is presented} alkyl chain. In fact, attempts to prepare (SF₅)₂NC₄F₉ have been unsuccessful thus far. The N-chloroamines were also reacted with simple olefins to give a variety of addition products such as SF₅N(CF₃)CH₂CH₂Cl, SF₅N(CF₃)CF₂CF₂Cl, SF₅N(C₂F₅)CH₂CH₂Cl, and SF₅N(C₄F₉)CH₂CH₂Cl.
