METHOD OF PRODUCING 1-PHENYL-2,3,4,5-TETRAALKYLBOROCYCLOPENTA-2,4-DIENES Russian patent published in 2009 - IPC C07F5/02 

Abstract RU 2376310 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 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 synthesis. A method is described for producing 1-phenyl-2,3,4,5-tetraalkylborocyclopenta-2,4-dienes by reacting dialkyl substituted acetylenes with phenyldichloroborane and magnesium metal in the presence of zirconocene dichloride as a catalyst in an argon atmosphere in a tetrahydrofuran medium. The reaction time is 8 to 12 hours and total output of end products is 35 to 55%.

EFFECT: obtaining novel organoboron compounds in a single step, synthesis of which is difficult or impossible using known methods.
