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.
