Hydroboration–oxidation reaction without THF

The first step of [hydroboration–oxidation](https://en.wikipedia.org/wiki/Hydroboration%E2%80%93oxidation_reaction) usually involves $\ce{BH3}$ accompanied by THF. Is it possible for hydroboration to occur without the presence of THF? Borane is incredibly reactive. Wouldn't it just react by itself without being stabilized by THF?




Borane dimerises to [diborane](https://en.wikipedia.org/wiki/Diborane) which does all the reactions of borane, including hydroborating alkenes. Diborane gas is commercially available if you wish to use it rather than stabilised borane, and have the equipment and skills to handle it. A number of other stabilisers are used for borane and are commercially available e.g. dimethyl sulfide, ammonia, triethylamine, pyridine.
