Primary amines such as ethylamine, pentylamine, and hexylamine are also converted to the corresponding N- alkylidenealkylamines. Secondary amines such as diethylamine, dipropylamine, and dibutylamine are dehydrogenated to the corresponding N- alkylidenealkylamines. When triethylamine is allowed to react,...
