“…All reactions with the reactive organosodium salts can occur on the surface of the aggregate, from which no pair of ions, much less a single one, need escape to react in solution. This idea is supported by three facts: The medium, pentane, is the poorest solvent known for ionic compounds, no solution of the reagent has ever been detected, and the amount of polymer approximately doubles and triples as the catalyst is proportionately increased (30), whereas no increase should have resulted in a solution already saturated by the reagent.…”
