hydroborationn.

/ˌhʌɪdrəʊbɔːˈreɪʃən/

Etymology: < hydro- comb. form + bor- (in boron n.) + -ation suffix.

Chemistry.

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, =B—H + C^_=C^_ → =B—C^_—C^_H.

hydroboration1957

1957 Brown & Rao in Jrnl. Org. Chem. 22 1136/2 (heading) Hydroboration of olefins. A remarkably fast room-temperature addition reaction of diborane to olefins.

1957 Brown & Rao in Jrnl. Org. Chem. 22 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.

1966 H. Steinberg & R. J. 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.

1971 Nature 20 Aug. 536/2 Many related organic syntheses depend on the hydroboration of acetylenes or dienes as the first step.
