Production Example 6 Synthesis of lithium n-butyltriphenylborate In a four-necked reaction vessel, 3.5 g (0.025 mol) of a boron trifluoride-ether complex was placed, and furthermore, 100 mL of tetrahydrofuran was placed and stirred. The contents were cooled to -20° C., and to the contents, 74 mL of a 1.0 molL-1 solution of phenylmagnesium bromide prepared by a routine procedure from bromobenzene was gradually added dropwise. The formation of triphenylborane and the completion of the reaction were confirmed by NMR, after which 12 mL of a 2.0 molL-1 cyclohexane solution of n-butyllithium (available from Aldrich) was added dropwise. After dropping, the contents were stirred for 2 hours at room temperature, were added with 100 mL of hexane to perform filtration, and were dried under reduced pressure to obtain an aimed product.
