Abstract 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 (BH2S3) 2. The reducing ability of Ba (BH2S3) 2 for the reduction of aldehydes, ketones, α, β-unsaturated carbonyl compounds, azides, nitro compounds. and ...
