The preparation of sodium malonyloxyborohydride in situ and its selective hydroborating alkene are described. It is confirmed by chemical reaction that the hydroboration of aliphatic terminal alkenes such as 1-heptene with sodium malonyloxyborohydride in THF involves the addition of 98% of boron atom moitey to the terminal position on the double bond and 2% at the 2-position to yield monosubstituted organoboron compounds, i.e. sodium malonyloxyborohydride is a monofunctional hydroborating reagent.
