Calcium amidoborane (Ca(NH2BH3)2, CaAB) is a new member of the borohydride family, which possesses interesting dehydrogenation features. CaAB also exhibits superior performance in chemoselective reduction. Our experimental results show that CaAB can reduce α,β-unsaturated carbonyl compounds chemoselectively to the corresponding allylic alcohols at ambient temperature.
