Many preparative reactions that are otherwise attractive are ruled out for use in the undergraduate organic chemistry laboratory by their long reaction time. Prolonged reaction times lead to student boredom and inactivity. A long reflux time or the requirement that a reaction stand overnight at room temperature will make it impossible to complete a preparative experiment in a single three-hour laboratory period.
