The first example of an efficient and direct dehydrogenative boration of alkenes for vinyl boronate ester synthesis was achieved using a zirconium catalyst. Our methodology avoids using precious transition metals, additional hydrogen acceptors, high temperatures, and long reaction times, which were required to overcome the reducing ability of borane, to give alkyl boronate esters. Detailed mechanistic studies revealed a reversible reaction pathway and further suggested applying the zirconium complex as a “shuttle catalyst” for transfer boration, which thus sidesteps the use of relatively sensitive borane.
Reaction of cyclopentadienyl zirconium derivatives with sterically encumbered arylaluminum hydrides: X-ray crystal structure of (η5-C5H5)2(H)Zr(μ 2-H)2Al(H)C6H2-2,4,6-Bu t3

The novel reactions between Cp2ZrMe2 (Cp=η5-C5H5) and (Mes*AlH)2 (Mes=C6H2-2,4,6-But3) to afford Cp2(H)Zr(μ2-H)2Al(Me)Mes* (1) and between Cp2Zr(Cl)H and [Mes*AlH3Li(THF)2]2 to give Cp2(H)Zr(μ2-H)2Al(H)Mes* (2) are described. The X-ray crystal structure and NMR spectroscopy of 1 indicate that, in the crystalline product, a methyl group has been transferred from zirconium to aluminum, and the metals have been connected by two hydrogen bridges. The compounds Cp2ZrH2 and Mes*AlMe2 were also obtained as reaction products in the synthesis of 1. The aluminum center is four-coordinate in contrast to the five- or six-coordination observed in previously published complexes. Compound 2, which is believed to have a very similar structure to that of 1, was obtained in moderate yield as a colorless crystalline material.
