Lewis acid induced N-methyleneamine equivalents from N-(methoxymethyl)anilines or 1,3,5-triphenylhexahydro-1,3,5-triazines reacted with propargyltrimethylsilanes to give N-buta-2,3-dienylanilines, 4-methylene-1,2,3,4-tetrahydroquinolines and its oxidized product of 4-methylquinolines. These products came from branching reactions of the elimination and electrophilic aromatic substitution from the same vinylic carbocation intermediate.
