摘要: Abstract The reaction of alkynyllithium reagents with methyl dialkylborinates in tetrahydrofuran proceeds readily to form lithium alkynyldialkylborinates. Reaction this ”rate“ complex 1.3 equivalent boron trifluoride diethyl etherate gives the alkynyldialkylboranes essentially quantitative yield.
