The fluorideioncatalyzed Oligomerization of F-vinylamines, such as F-(N,N-dimethylvinylamine), F-(N-vinylmorpholine) and F-(N-vinylpyrrolidine), was investigated. It was found that dimers were obtained in high yields when the reaction was conducted in aprotic polar solvents, especially in DMF using cesium fluoride as a fluorideion source. Attempts to obtain oligomers higher than dimers failed. The
