Zinc bis-tetrahydroborate forms a solid complex with dimethylformamide (DMF) of composition, Zn(BH4)2 1.5DMF. Unlike zinc bis-tetrahydroborate itself, the complex with DMF can be stored as a solid at room temperature. Ketones and aldehydes are reduced to the corresponding alcohols by the complex but the mechanism of reduction appears to be different from that using zinc bis-tetrahydroborate itself

A one-pot, three-step method for highly enantioselective C3-allylation reactions of pyridines was developed. The method involved borane-catalyzed dearomative pyridine hydroboration, palladium-catalyzed enantioselective allylation of the dearomatized intermediate, and finally oxidation by air. The method was applicable to a broad range of pyridines, N-heteroarenes, and allylic esters.
