METHOD OF PRODUCING 1-BROMO-3-ALKYLBOROLANES Russian patent published in 2014 - IPC C07F5/02 

FIELD: chemistry.

SUBSTANCE: present invention relates to production of organoboron compounds. The method is carried out by reacting α-olefins with triethylaluminium in the presence of a zirconocene dichloride catalyst in an atmosphere of argon at temperature of -20°C for 6 hours, followed by cooling the reaction mass to -60°C. Boron bromide is then added in double the amount relative to AlEt₃ in a medium of hexane and mixed at temperature of -20°C for 30-60 minutes. Tetrahydrofuran is then added to the reaction mass cooled to -60°C immediately before rectification.

EFFECT: invention enables to obtain organoboron compounds which can be used as components of catalyst systems in oligomerisation and polymerisation of olefin, diene and acetylene hydrocarbons, as well as in fine organic and organometallic syntheses.
