To a mixture of tert-butyl-but-3-ynyloxy-dimethyl-silane (I) (1.0 g, 7.14 mmol) and 4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (II) (958 mg, 7.49 mmol) were added bis(cyclopentadienyl)zirconium chloride hydride (183 mg, 0.714 mmol) and triethylamine (72 mg, 0.714 mmol). The resulting mixture was heated at 60° C. for 6 hours and was diluted with hexanes. The precipitate was removed by filtering over a short pad of silica gel and washed with hexanes. The filtrate was concentrated and dried through vacuum to give 1.76 g (93%) of the title compound as a colorless liquid.
