Reduction of Organic Halides with Sodium and Potassium Gallium Hydrides and Chemoselective Reduction of Organic Halides with Potassium Gallium Hydride in Multifunctional Compounds

But most of them have been reducing agent containingboron or aluminum. In general, it has been known that some-what powerful agents are necessary to reduce organichalides. This means practically very difficult to reduce halo-gen group selectively in organohalogen compounds contain-ing other functional groups. During the reaction rate studiesof metal gallium hydrides on various functional groups, wefound that lithium, sodium, and potassium gallium hydrideexhibited excellent reducing power for the reduction of alkylhalides to the corresponding alkane, although the hydridesshowed mild reducing characteristics to reduce only alde-hydes and ketones.
