hydroboration Chem.|ˌhaɪdrəʊbɔəˈreɪʃən|
[f. hydro- + boron + -ation.]
The addition of a linked boron–hydrogen pair of atoms in a molecule across a double or triple bond between a carbon atom and another atom; for example, {b2}B{b1}H + C{btc1}{bbc1}{b2}C{btc1}{bbc1} → {b2}B{b1}C{btc1}{bbc1}{b1}C{btc1}{bbc1}H.
1957Brown & Rao in Jrnl. Org. Chem. XXII. 1136/2 (heading) Hydroboration of olefins. A remarkably fast room-temperature addition reaction of diborane to olefins. Ibid. 1138/2 The hydroboration reaction should provide a useful and convenient synthetic route for the transformation of olefins into organoboranes, alcohols, and other functional derivatives. 1966Steinberg & Brotherton Organoboron Chem. II. viii. 225 The reaction sequence can be formulated to involve hydroboration of the carbon–nitrogen triple bond followed by a hydrogen shift and final cyclization. 1971Nature 20 Aug. 536/2 Many related organic syntheses depend on the hydroboration of acetylenes or dienes as the first step. |
