Organic-soluble borohydride. For references to reduction by borohydride, see Sodium borohydride, 35788. Changing the counter ion permits variation in reactivity and selectivity.

/n

Amides and nitriles are selectively reduced in dichloromethane: Heterocycles, 14, 1437, 1441 (1980); aryl ester, nitro or halo-substituents are unaffected. For the 1,4-reduction of enones, see: Tetrahedron, 37, 1171 (1981). Carboxylic acids can be reduced to alcohols by refluxing in DCM: Synth. Commun., 30, 941 (2000).

/n

With reactive halides (e.g. MeI) in DCM, provides a convenient source of diborane: Tetrahedron Lett., 3173 (1972). Hydroboration of alkenes has also been effected by refluxing with the reagent in chloroform: Indian J. Chem., 37B, 1186 (1998).

Effective regent for cleavage of TMS ethers: Synth. Commun., 26, 1065 (1996).
