The influence of phase transfer catalyst structure on a branching of reaction paths is recorded.An almost complete change-over of mechanisms can be achieved.Reaction of allyl bromide with bromoform/sodium hydroxide/catalyst yields carbene adduct 1 and displacement products 2 and 3.Two new and unusual catalysts, AsPh4Cl and Cl, give substitution:addition 10:1, whereas NMe4Cl and benzo-15-crown-5 lead to 1:4, both at high conversions.

REACTION OF ALLYL HALIDES WITH HALOFORMS AND ALKALI UNDER THE CONDITIONS OF INTERPHASE CATALYSIS

The reaction of allyl halides with haloforms and alkali in the presence of interphase transfer catalysts gives cyclopropanes and 4,4,4-trihalogeno-1-butenes.The latter are formed by nucleophilic substitution of the halogen in the allyl halide by the trihalogenomethyl anion.
