Method for preparation of gem-diboron compound by olefin selective 1, 1-diboronation

The invention relates to a method for preparation of a gem-diboron compound by olefin selective 1, 1-diboronation. The method includes: dissolving an olefin compound, a cyclopentadienyl early transition metal catalyst and an alkali compound in a solvent, then adding a borane compound, carrying out reaction at 60-150DEG C for 1-16h in a protective atmosphere, and then carrying out separation to obtain the gem-diboron compound. The method is simple and convenient to operate, low in cost, and high in reaction atom economy, and is suitable for industrial production.

Preparation method and application of geminal diboron compound

The invention discloses a preparation method and application of a geminal diboron compound. The preparation method includes: in a protective atmosphere, subjecting a uniform mixture system of a carbonyl compound, a diboron reagent, an iron catalyst, an alkaline substance, a proton source and a solvent to reaction at 60-150 DEG C for 3-36 h, and separating to obtain the geminal diboron compound. The preparation method herein constructs, in one step, the geminal diboron compound which is difficult to efficiently implement in the past, from simple, economical and easily accessible materials as substrates under catalyst of the iron catalyst; the geminal diboron compound has a good application prospect in the sciences of pharmaceutical synthetic intermediates and organic photoelectric materials; the preparation method herein helps solve the problem that the field of traditional preparation of geminal diboron compounds requires pre-functionalization or some substrates are incompatible; the reaction conditions are relatively mild; operation is simple; the raw materials are economical and easy to attain; the reaction efficiency is high; the preparation method herein provides good functional group compatibility.

Synthesis of 1,1-organodiboronates via Rh(I)CI-catalyzed sequential regioselective hydroboration of 1-alkynes

A Rh(I)Cl-DPPB-complex-catalyzed sequential hydroboration of aryl alkynes and aliphatic alkynes was achieved. The reaction proceeded with almost perfect regioselectivity to afford 1,1-organodiboronate compounds in moderate to good yield. Georg Thieme Verl
