Literature References

In the presence of TMS chloride or TiCl4, converts alkenes to the anti-Markovnikov alcohols in good yield: J. Chem. Soc., Chem. Commun., 903 (1989); Tetrahedron Lett., 34, 171 (1993).

In combination with TMS chloride, selectively reduces carboxylic acids to alcohols; esters, lactones, nitro- and chloro-substituents are unaffected: Synth. Commun., 20, 907 (1990). For example and reaction scheme, see 4-Nitrobenzoic acid, A14738. See also Tetra-n-butyl­ammonium borohydride, A17494.
