Reaktionssteuerung durch die Struktur eines Phasentransfer-Katalysators bei Tribrommethyl-Anion-/Dibromcarben-Umsetzungen

Control of Reactions with Tribromomethyl Anions/Dibromocarbene by the Nature of the Phase Transfer Catalyst Conversion of (substituted) allyl bromides with bromoform/sodium hydroxide/phase transfer catalyst may be directed towards dibromocarbene addition or substitution by tribromomethyl anion by choice of the catalyst.The observed effects (addition: substitution in the primary step variable between maximally 92:1 and 1:91) are by far the largest reported for specific catalyst influences.Small, hard cations favor the carbene route, sterically shielded and highly delocalized ones favor the substitution process.

Steuerung einer Reaktionsverzweigung durch geeignete Phasentransfer-Katalysatoren. Anwendungen der Phasentransfer-Katalyse 37.

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.

Novel pyrimidinyl ethers, their use as herbicides, herbicidal compositions comprising said pyrimidinyl ethers and processes for the preparation thereof

Pyrimidines having an amino group in the 2-position and a cyclopropylmethoxy group in the 4-position of the pyrimidine nucleus. Compounds according to the invention have valuable herbicidal activity, particularly after pre-emergence application in cotton and sunflower.

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.
