In this context, (Caffeine)(tetrahydroborato)zinc complex as white stable reducing agents [Zn(BH₄)₂(caf)], has been prepared by  complexation of oneequimolar amounts of zinc tetrahydroborate and one equimolar amounts of caffeine at room temperature. Also, [Zn(BH₄)₂(caf)]has been used for reduce of a variety of carbonyl compounds such as aldehydes, ketones, α, β-unsaturated carbonyl compounds, acyloins and a-diketones to their corresponding alcohols in excellent yields (90-95%). The reduction reactions have been completed in appropriate times (30-90 min) by using of 0.5-1 equivalents of [Zn(BH₄)₂(caf)] in CH₃CN at room temperature or under reflux conditions.
