Sulfurated Calcium, magnesium, and berelium horohydrides are prepared by metathetical reaction between NaBH2S3 and Ca, Mg, and Be chlorides in dry THF and the effect of metal cation exchange on their stability and reactivity has been presented. In this study we have shown that Ca(BH2S3)2 is much more stable and more reactive than its Mg, Be, and Na analogues. Ca(BH2S3)2can easily reduce carbonyl compounds such as aldehydes, ketones, acyloins, α-diketones, α-β-unsaturated carbonyl compounds, aroyl azides, and carboxylic acid chlorides to their corresponding alcohols in good to excellent yields. Epoxides are also effected by this reagent and produce their symmetrical dihydroxydisulfides in good yields.

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 cleavage of epoxides in dry THF is described.
