How to Make Organolithium Reactions Reproducible: Lock Down the Effective Equivalents, Aggregation State, and the Addition/Temperature-Control Window

In practice, you may often encounter situations like these: the same recipe, the same substrate, even the same bottle of n-BuLi solution (i.e., an organic-solvent solution of n-butyllithium, n-BuLi), yet the results drift noticeably.
