METHOD FOR PREPARING CATECHOL BORANE Russian patent published in 2003 - IPC

Abstract RU 2206569 C1

FIELD: technology of organoboron compounds. SUBSTANCE: invention relates to method for preparing catechol borane that can be used as a monofunctional hydroborating agent for alkenes and alkynes. Invention describes method for preparing catechol borane by interaction of pyrocatechol with diborane in diethyl ether medium at temperature (-10)-(10) C in the mole ratio pyrocatechol : diborane = 1 : (0.4-0.5), respectively. Then reactive mass is kept at temperature 0-35 C and blown off with inert gas. Method ensures to obtain catechol borane with the yield 88.0-92.0% and high purity 99.7-100.0%. EFFECT: improved preparing method, increased yield, improved purity.
