Bromobenzene → Triphenylborane

関与物質

反応手順

In the case of the tetramethylammonium methyl triphenyl borate, concretely, its production is performed by reacting phenyl bromide with magnesium in diethyl ether to prepare a Grignard reagent, dripping it in a solution of boron trifluoride diethyl etherate in diethyl ether, and then stirring for several hours to obtain triphenylborane, followed by addition of methyllithium without isolating triphenylborane to convert it to lithium methyl triphenyl borate and by addition of tetramethylammonium bromide to effect ion exchange to obtain tetramethylammonium methyl triphenyl borate.
