Barium and strontium sulfurated borohydrides, Ba(BH2S3)(2),Sr(BH2S3)(2) the two newly introduced modified borohydride agents, are prepared from NaBH2S3 by metathesis reaction with BaCl2 and SrCl2 in good yields. Ba(BH2S3)(2) is more stable and more reactive than Sr(BW2S3)(2) The reducing ability of Ba(BH2S3)(2) for the reduction of aldehydes, ketones, alpha,beta -unsaturared carbonyl compounds, azides, nitro compounds, and cleavage of epoxides in dry THF is described.
