Unprecedented acceleration in the rate of the N-heterocyclic carbene (NHC) organocatalysis was observed while performing the reaction in water medium with NaCl as an additive during the synthesis of diverse spirooxindole-γ-butyrolactone derivatives. The seminal role of hydrophobic hydration effect for the acceleration of the reaction was further proved by performing the reaction with antihydrophobic
