The reactions of seven iV-(2-triphenylstannylethyl) amines (3a-g), prepared from the corresponding 2-chloroethylamines (la-e, g) and triphenyltinlithium (2), with methyl halides (MeX) or hydrogen halides (HX) were investigated. In the case of X= I or Br, the quaternary ammonium salts or the amine hydrohalides,. produced from A'-(2-triphenylstannylethy1) alkylamines (3a and 3b), were unstable and were cleaved by nucleophilic attack of X-at tin ...
