METHOD OF OBTAINING PYRIDINATES OF 1-FLUORO(CHLORO)-3-ALKYL(ARYL)BOROLANES Russian patent published in 2014 - IPC C07F5/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining pyridinates of 1-fluoro(chloro)-3-alkyl(aryl)borolanes of general formula (1), where R=Bu, X=F (a); R=Hex, X=F (b); R=Hex, X=Cl (c); R=Bn, X=Cl (d). The method includes the interaction of unsaturated compounds, selected from the group of hex-1-ene, oct-1-ene or allylbenzene, with triethylaluminium (AlEt₃) in the presence of a catalyst (Cp₂ZrCl₂) in a ratio of 10:12:0.5 in hexane in an atmosphere of inert gas with mixing for 7 h, addition of boron trifluoride etherate (BF₃·Et₂O) or boron chloride (BCl₃) and pyridine in a double with respect to AlEt₃ amount, following mixing at room temperature for 30-60 min.

EFFECT: obtained compounds can be applied as components of catalytic systems in processes of oligo- and polymerisation of olefin, diene and acetylene hydrocarbons, as well as in fine organic and organometallic synthesis.
