The reaction of alkynyllithium reagents with methyl dialkylborinates in tetrahydrofuran proceeds readily to form lithium methyl alkynyldialkylborinates. Reaction of this ”rate“ complex with 1.3 equivalent of boron trifluoride diethyl etherate gives the alkynyldialkylboranes in essentially quantitative yield.
炔基锂试剂与二烷基硼酸甲酯在四氢呋喃中的反应易于进行,以形成甲基炔基二烷基硼酸锂。该“速率”络合物与1.3当量的三氟化硼二乙基醚化物的反应以基本上定量的产率得到炔基二烷基硼烷。
