The situation: Beside the relevant inventory in the Merck index, organic-chemistry.org lists 243 name reactions (as counted on 08-Feb-2018), the compilation by Kurti and Czako includes "250 selections" (to quote K.C. Nicolaou's introduction), Li's general reference on the topic "covers over 320 classical as well as contemporary name reactions" yet he equally compiled name reactions relevant to heterocyclic compounds to mention a few possible sources. There may be a significant overlap of content, though. The discern of nucleophile and electrophile, as pointed out here, or sometimes anthromorphisms like
"What would you do if *you* were an electron"
(Grossmann book) to ease drawing mechanisms are ackowledged, too.
The question: But, isn't there a more condensed list consisting of maybe 50 to 100 organic name reactions most often used reliably in small molecule organic chemistry? As one possibility for "reliable" I think of reactions potentially used on larger scale (kg-lab, or journals like Org. Process Res. Dev.) or the ones suggested by computers in the course of an automated retrosynthetic analysis.
