The influence of phasetransfer catalyst structure on a branching of reaction paths is recorded. An almost complete change-over of mechanisms can be achieved. Reaction of allylbromide with bromoform/sodium hydroxide/catalyst yields carbene adduct and displacement products and . Two new and unusual catalysts, AsPh4Cl and [Ph3PNPPh3] Cl, give substitution: addition ~10:1, wheras NMe4Cl and benzo-15-crown-5
