METHOD OF OBTAINING 1-FLUORO-2-ALKYLBORACYCLOPROPANES Russian patent published in 2015 - IPC C07F5/02

Abstract RU 2561500 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining 1-fluoro-2-alkylboracyclopropanes of general formula where R = n-C₄H₉, n-C₆H₁₃, n-C₈H₁₇, n-C₁₂H₂₅. Method includes interaction of α-olefin (hex-1-ene, oct-1-ene, dec-1-ene, tetradec-1-ene) with tetrahydrofurane complex of boron fluoride BF₃·TGF in presence of Mg (powder) and catalyst Cp₂TiCl₂ in tetrahydrofurane. Method is realised in inert atmosphere with cooling reaction mass to 0°C for 1 h and further mixing at room temperature (~ 20-22°C) for 12-16 hours with molar ratio α-olefin : BF₃·THF : Mg : Cp₂TiCl₂ = 10 : (10÷30) : (20÷40) : (1.8÷2.2).

EFFECT: invention makes it possible to obtain novel boron compounds, which can be applied as catalytic systems in processes of oligo- and polymerisation of olefin, diene and acetylene hydrocarbons, as well as in fine organic and organometallic synthesis.
